Constructor Detail

EcdsaSignatureImplKeychain

public EcdsaSignatureImplKeychain()

EcdsaSignatureImplKeychain

public EcdsaSignatureImplKeychain(com.entrust.toolkit.security.crypto.signature.DigitalSignatureImpl.DigestAlgorithmInfo algInfo)

The constructor; creates a new EcdsaSignatureImplKeychain instance.

This constructor is provided for digital signature algorithms for which the digest algorithm is fixed and is set at algorithm instantiation time (ex: SHA1withECDSA). Manual digest algorithm configuration via setDigestAlgInfo(DigestAlgorithmInfo) is not required and should not be done.

Parameters:

algInfo - information about this digest algorithm used with digital signature algorithm implementation
