Method Detail

getJdkSignature

public static java.security.Signature getJdkSignature(java.lang.String jdkSignatureAlgo)

Return a java.security.Signature. The required algorythm is usually generated from Algorithms:

  Algorithms.jdkSignatureName(DigestAlgoEnum.XXX, KeyEnum.XXX)
 

Parameters:

jdkSignatureAlgo - signature algorythm required in JDK format

Returns:

the Signature

Throws:

JsdsiRuntimeException - on error

getJdkSignature

public static java.security.Signature getJdkSignature(java.lang.String jdkSignatureAlgo,
                                                      java.lang.String provider)

Return a java.security.Signature. The required algorythm is usually generated from Algorithms:

  Algorithms.jdkSignatureName(DigestAlgoEnum.XXX, KeyEnum.XXX)
 

Parameters:

jdkSignatureAlgo - signature algorythm required in JDK format

provider - the Provider to use

Returns:

the Signature

Throws:

JsdsiRuntimeException - on error

getDigesterForJdkSignature

public static java.security.MessageDigest getDigesterForJdkSignature(java.lang.String jdkSignatureAlgo)
