List of initSign() Examples

Examples of initSign()

com.sun.org.apache.xml.internal.security.algorithms.SignatureAlgorithm.initSign()
Proxy method for {@link java.security.Signature#initSign(java.security.PrivateKey)}which is executed on the internal {@link java.security.Signature} object. @param signingKey @throws XMLSignatureException
java.security.Signature.initSign()
Initialize this object for signing. If this method is called again with a different argument, it negates the effect of this call. @param privateKey the private key of the identity whose signatureis going to be generated. @exception InvalidKeyException if the key is invalid.
org.apache.harmony.security.tests.support.MySignature1.initSign()
org.apache.xml.security.algorithms.SignatureAlgorithm.initSign()
Proxy method for {@link java.security.Signature#initSign(java.security.PrivateKey)}which is executed on the internal {@link java.security.Signature} object. @param signingKey @throws XMLSignatureException
org.bouncycastle.openpgp.PGPSignatureGenerator.initSign()
Initialise the generator for signing. @param signatureType @param key @throws PGPException
org.bouncycastle.openpgp.PGPV3SignatureGenerator.initSign()
Initialise the generator for signing. @param signatureType @param key @throws PGPException
org.keyczar.interfaces.SigningStream.initSign()
Initializes this stream for signing. @throws KeyczarException If any Java JCE errors occur
