RSA algorithm.

ECDSA

public static final SignatureAlgorithm ECDSA

ECDSA algorithm.

DSA

public static final SignatureAlgorithm DSA

DSA algorithm.

Field Detail

keyAlgorithm

public final java.lang.String keyAlgorithm

Name of the private key as reported by PrivateKey.

minSdkVersion

public final int minSdkVersion

Minimum SDK version that allows this signature.

signatureAlgorithmSuffix

public final java.lang.String signatureAlgorithmSuffix

Method Detail

values

public static SignatureAlgorithm[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SignatureAlgorithm c : SignatureAlgorithm.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SignatureAlgorithm valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromKeyAlgorithm

public static SignatureAlgorithm fromKeyAlgorithm(java.lang.String keyAlgorithm,
                                                  int minSdkVersion)
                                           throws java.security.NoSuchAlgorithmException

Obtains the signature algorithm that corresponds to a private key name applicable to a SDK version.

Parameters:

keyAlgorithm - the named referred in the PrivateKey

minSdkVersion - minimum SDK version to run

Returns:

the algorithm that has keyAlgorithm equal to keyAlgorithm

Throws:

java.security.NoSuchAlgorithmException - if no algorithm was found for the given private key; an algorithm was found but is not applicable to the given SDK version

signatureAlgorithmName

public java.lang.String signatureAlgorithmName(DigestAlgorithm digestAlgorithm)

Obtains the name of the signature algorithm when used with a digest algorithm.

Parameters:

digestAlgorithm - the digest algorithm to use

Returns:

the name of the signature algorithm
