Java Security Standard Algorithm Names

The Java SE Security API requires and uses a set of standard names for algorithms, certificate and keystore types. You can find a list of standard algorithm names in this document.

Note that an SE implementation may support additional algorithms that are not defined in this specification. As a best practice, if an algorithm is defined in a subsequent version of this specification and an implementation of an earlier specification supports that algorithm, the implementation should use the standard name of the algorithm that is defined in the subsequent specification. Each SE implementation should also document the algorithms that it supports or adds support for in subsequent update releases. The algorithms may be documented in release notes or in a separate document such as the JDK Security Providers document.

In some cases naming conventions are given for forming names that are not explicitly listed, to facilitate name consistency across provider implementations. Items in angle brackets (such as <digest> and <encryption>) are placeholders to be replaced by a specific message digest, encryption algorithm, or other name.

Note: Standard names are not case-sensitive.

Note: The JDK Security Providers document contains specific provider and algorithm information.

CertificateFactory Types

The type in this section can be specified when generating an instance of CertificateFactory.

CertPath Encodings

The following encodings may be passed to the getEncoded method of CertPath or the generateCertPath(InputStream inStream, String encoding) method of CertificateFactory.

Encoding Description
PKCS7 A PKCS #7 SignedData object, with the only significant field being certificates. In particular, the signature and the contents are ignored. If no certificates are present, a zero-length CertPath is assumed.

Warning: PKCS #7 does not maintain the order of certificates in a certification path. This means that if a CertPath is converted to PKCS #7 encoded bytes and then converted back, the order of the certificates may change, potentially rendering the CertPath invalid. Users should be aware of this behavior.

See PKCS #7: Cryptographic Message Syntax for details on PKCS #7.
PkiPath An ASN.1 DER encoded sequence of certificates, defined as follows:

PkiPath ::= SEQUENCE OF Certificate

Within the sequence, the order of certificates is such that the subject of the first certificate is the issuer of the second certificate, and so on. Each certificate in PkiPath shall be unique. No certificate may appear more than once in a value of Certificate in PkiPath. The PkiPath format is defined in defect report 279 against X.509 (2000) and is incorporated into Technical Corrigendum 1 (DTC 2) for the ITU-T Recommendation X.509 (2000). See the ITU web site for details.

Cipher Algorithm Modes

The following names can be specified as the mode component in a transformation when requesting an instance of Cipher.

Algorithm Name Description
NONE No mode.
CBC Cipher Block Chaining Mode, as defined in FIPS PUB 81.
CCM Counter/CBC Mode, as defined in NIST Special Publication SP 800-38C.
CFB, CFBx Cipher Feedback Mode, as defined in FIPS PUB 81.

Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher's actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the "DES/CFB8/NoPadding" and "DES/OFB32/PKCS5Padding" transformations. If no such number is specified, a provider-specific default is used. (For example, the SunJCE provider uses a default of 64 bits for DES.) Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8-bit mode such as CFB8 or OFB8.
CTR A simplification of OFB, Counter mode updates the input block as a counter.
CTS Cipher Text Stealing, as described in Bruce Schneier's book Applied Cryptography-Second Edition, John Wiley and Sons, 1996.
ECB Electronic Codebook Mode, as defined in FIPS PUB 81 (generally this mode should not be used for multiple blocks of data).
GCM Galois/Counter Mode, as defined in NIST Special Publication SP 800-38D.
OFB, OFBx Output Feedback Mode, as defined in FIPS PUB 81.

Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher's actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the "DES/CFB8/NoPadding" and "DES/OFB32/PKCS5Padding" transformations. If no such number is specified, a provider-specific default is used. (For example, the SunJCE provider uses a default of 64 bits for DES.) Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8-bit mode such as CFB8 or OFB8.
PCBC Propagating Cipher Block Chaining, as defined by Kerberos V4.

Cipher Algorithm Paddings

The following names can be specified as the padding component in a transformation when requesting an instance of Cipher.

Algorithm Name Description
NoPadding No padding.
ISO10126Padding This padding for block ciphers is described in 5.2 Block Encryption Algorithms in the W3C "XML Encryption Syntax and Processing" document.
OAEPPadding, OAEPWith<digest>And<mgf>Padding Optimal Asymmetric Encryption. Padding scheme defined in PKCS #1, where <digest> should be replaced by the message digest and <mgf> by the mask generation function. Examples: OAEPWithMD5AndMGF1Padding and OAEPWithSHA-512AndMGF1Padding.

If OAEPPadding is used, Cipher objects are initialized with a javax.crypto.spec.OAEPParameterSpec object to supply values needed for OAEPPadding.
PKCS1Padding The padding scheme described in PKCS #1 v2.2, used with the RSA algorithm.
PKCS5Padding The padding scheme described in PKCS #5: Password-Based Cryptography Specification, version 2.1.
SSL3Padding The padding scheme defined in the SSL Protocol Version 3.0, November 18, 1996, section 5.2.3.2 (CBC block cipher):

block-ciphered struct {
    opaque content[SSLCompressed.length];
    opaque MAC[CipherSpec.hash_size];
    uint8 padding[GenericBlockCipher.padding_length];
    uint8 padding_length;
} GenericBlockCipher;

The size of an instance of a GenericBlockCipher must be a multiple of the block cipher's block length. The padding length, which is always present, contributes to the padding, which implies that if:

sizeof(content) + sizeof(MAC) % block_length = 0,

padding has to be (block_length - 1) bytes long, because of the existence of padding_length.

This makes the padding scheme similar (but not quite) to PKCS5Padding, where the padding length is encoded in the padding (and ranges from 1 to block_length). With the SSL scheme, the sizeof(padding) is encoded in the always present padding_length and therefore ranges from 0 to block_length-1.

Configuration Types

The type in this section can be specified when generating an instance of javax.security.auth.login.Configuration.

Type Description

Service Attributes

The attributes in this section are for cryptographic services. The service attributes can be used as filters for selecting providers.

A cryptographic service is always associated with a particular algorithm or type. For example, a digital signature service is always associated with a particular algorithm (for example, DSA), and a CertificateFactory service is always associated with a particular certificate type (for example, X.509).

Note: The attribute name and value are case-insensitive.

Attribute Description
KeySize The maximum key size that the provider supports for the cryptographic service.
ImplementedIn Whether the implementation for the cryptographic service is done by software or hardware. The value of this attribute is "software" or "hardware".
ValidationAlgorithm The name of the specification that defines the certification path validation algorithm that an implementation of CertPathBuilder or CertPathValidator supports. RFCs should be specified as "RFC#" (ex: "RFC5280") and Internet Drafts as the name of the draft (ex: "draft-ietf-pkix-rfc2560bis-01.txt"). Values for this attribute that are specified as selection criteria to the Security.getProviders method will be compared using the String.equalsIgnoreCase method. All PKIX implementations of CertPathBuilder and CertPathValidator should provide a value for this attribute.
LDAPSchema The name of the specification that defines the LDAP schema that an implementation of an LDAP CertStore uses to retrieve certificates and CRLs. The format and semantics of this attribute is the same as described for the ValidationAlgorithm attribute. All LDAP implementations of CertStore should provide a value for this attribute.
ThreadSafe Whether a SecureRandom implementation has its SecureRandomSpi engine methods implemented thread safe.

For example,

    map.put("KeyPairGenerator.DSA",
            "sun.security.provider.DSAKeyPairGenerator");
    map.put("KeyPairGenerator.DSA KeySize", "2048");

<digest>with<encryption> Use this to form a name for a signature algorithm with a particular message digest (such as MD2 or MD5) and algorithm (such as RSA or DSA), just as was done for the explicitly defined standard names in this section (MD2withRSA, and so on).

For the signature schemes defined in PKCS #1 v2.2, for which the <digest>with<encryption> form is insufficient, <digest>with<encryption>and<mgf> can be used to form a name. Here, <mgf> should be replaced by a mask generation function such as MGF1. Example: MD5withRSAandMGF1

For the signature formats defined in IEEE P1363, <digest>with<encryption>in<format>Format can be used to form a name. Example: SHA1withECDSAinP1363Format

Algorithm Name Description
PKIX A factory for X509ExtendedTrustManager objects that validate certificate chains according to the rules defined by the IETF PKIX working group in RFC 5280 or its successor. The TrustManagerFactory must support initialization using the class javax.net.ssl.CertPathTrustManagerParameters.

XML Signature (XMLSignatureFactory/KeyInfoFactory/TransformService) Mechanisms

The mechanism that can be specified when generating an instance of XMLSignatureFactory, KeyInfoFactory, or TransformService.

The mechanism identifies the XML processing mechanism that an implementation uses internally to parse and generate XML signature and KeyInfo structures. Also, note that each TransformService instance supports a specific transform algorithm in addition to a mechanism. The standard names for the transform algorithms are defined in the next section.

Mechanism Description
DOM The Document Object Model.

XML Signature Transform (TransformService) Algorithms

The algorithms in this section can be specified when generating an instance of TransformService.

Note: The URIs are specified instead of names to be consistent with the XML Signature standard. API constants have been defined for each URI, and are listed in parentheses after each URI in the following table.

JSSE Cipher Suite Names

The following table contains the standard JSSE cipher suite names. Over time, various groups have added additional cipher suites to the SSL/TLS/DTLS namespace.

Some JSSE cipher suite names were defined before TLSv1.0 was finalized, and were therefore given the SSL_ prefix. The names mentioned in the TLS RFCs prefixed with TLS_ are functionally equivalent to the JSSE cipher suites prefixed with SSL_.

Additional JSSE Standard Names

Key Types

The keyType parameter passed to the chooseClientAlias, chooseServerAlias, getClientAliases, and getServerAliases methods of X509KeyManager specifies the public key types.

Each row of the table that follows lists the standard name that should be used for keyType, given the specified certificate type.

Standard Names for a Key Type
Name Certificate Type
RSA RSA
DSA DSA
DH_RSA Diffie-Hellman with RSA signature
DH_DSA Diffie-Hellman with DSA signature
EC Elliptic Curve
EC_EC Elliptic Curve with ECDSA signature
EC_RSA Elliptic Curve with RSA signature
RSASSA-PSS RSASSA-PSS

Protocols

The protocols parameter passed to the setEnabledProtocols method of SSLSocket and SSLEngine specifies the protocol versions to be enabled for use on the connection. The table that follows lists the standard names that can be passed to the setEnabledProtocols method or that may be returned by the getSupportedProtocols and getEnabledProtocols methods of SSLSocket and SSLEngine.

These names also apply to the protocol parameter returned from the getProtocol method of SSLSession, and the protocols parameter passed to the setProtocols method or that may be returned by the getProtocols method of SSLParameters.

Standard Names for a Protocol
Name Protocol
SSLv2 SSL version 2 protocol
SSLv3 SSL version 3 protocol
TLSv1 TLS version 1.0 protocol (defined in RFC 2246)
TLSv1.1 TLS version 1.1 protocol (defined in RFC 4346)
TLSv1.2 TLS version 1.2 protocol (defined in RFC 5246)
TLSv1.3 TLS version 1.3 protocol (defined in RFC 8446)
DTLSv1.0 DTLS version 1.0 protocol (defined in RFC 4347)
DTLSv1.2 DTLS version 1.2 protocol (defined in RFC 6347)
SSLv2Hello Currently, the SSLv3, TLSv1, and TLSv1.1 protocols allow you to send SSLv3, TLSv1, and TLSv1.1 hellos encapsulated in an SSLv2 format hello. For more details on the reasons for allowing this compatibility in these protocols, see Appendix E in the appropriate RFCs (previously listed).

Note: Some SSL/TLS servers do not support the v2 hello format and require that client hellos conform to the SSLv3 or TLSv1 client hello formats.

The SSLv2Hello option controls the SSLv2 encapsulation. If SSLv2Hello is disabled on the client, then all outgoing messages will conform to the SSLv3/TLSv1 client hello format. If SSLv2Hello is disabled on the server, then all incoming messages must conform to the SSLv3/TLSv1 client hello format.

Authentication Types

The authType parameter passed to the checkClientTrusted and checkServerTrusted methods of X509TrustManager indicates the authentication type. The table that follows specifies what standard names should be used for the client or server certificate chains.

Standard Names for Client or Server Certificate Chain
Client or Server Certificate Chain Authentication Type Standard Name
Client Determined by the actual certificate used. For instance, if RSAPublicKey is used, the authType should be "RSA".
Server The key exchange algorithm portion of the cipher suites represented as a String, such as "RSA" or "DHE_DSS".

Note: For some exportable cipher suites, the key exchange algorithm is determined at runtime during the handshake.

For instance, for TLS_RSA_EXPORT_WITH_RC4_40_MD5, the authType should be "RSA_EXPORT" when an ephemeral RSA key is used for the key exchange, and "RSA" when the key from the server certificate is used. Or it can take the value "UNKNOWN".

Endpoint Identification Algorithms

The endpoint identification algorithm indicates the endpoint identification or verification procedures during SSL/TLS/DTLS handshaking. The algorithm name can be passed to the setEndpointIdentificationAlgorithm method of javax.net.ssl.SSLParameters.

The following table shows the standard endpoint identification names.

Endpoint Identification Algorithm Name
Endpoint Identification Algorithm Name Specification
HTTPS RFC 2818
LDAPS RFC 2830

DSA Parameter Generation Algorithm
Field Description
Names DSA
Type AlgorithmParameterGenerator
Description This algorithm is the parameter generation algorithm described in NIST FIPS 186 for DSA.
Strength The length, in bits, of the modulus p. This must be a multiple of 64, ranging from from 512 to 1024 (inclusive), 2048, or 3072.
Alternatively, generate DSA parameters with the DSAGenParameterSpec class. Note that this class supports the latest version of DSA standard, FIPS PUB 186-3, and only allows certain length of prime P and Q to be used. Valid sizes for length of prime P and sub-prime Q in bits are as follows:

(1024, 160)
(2048, 224)
(2048, 256)
(3072, 256)

Security Algorithm Implementation Requirements

This section defines the security algorithm requirements for Java SE implementations. The security algorithm requirements are intended to improve the interoperability of Java SE implementations and applications that use these algorithms.

Note: The requirements in this section are not a measure of the strength or security of the algorithm. For example, recent advances in cryptanalysis have found weaknesses in the strength of the DESede (Triple DES) cipher algorithm. It is your responsibility to determine whether the algorithm meets the security requirements of your application.

Every implementation of this version of the Java SE platform must support the specified algorithms in the table that follows. These requirements do not apply to 3rd party providers. Consult the release documentation for your implementation to see if any other algorithms are supported.
