Interface PublicKey

All Known Implementing Classes:

DSAKey, RSAKey

public interface PublicKey

Interface for public key implementations, such as RSAKey or DSAKey. Such a key may be used to verify signatures.

Since:

4.0

Method Summary

boolean	verify(byte[] data, int dataOffset, int dataLength, byte[] sig) Verify a signature.
boolean	verify(byte[] data, int dataOffset, int dataLength, byte[] sig, int sigOffset, int sigLength) Verify a signature.

Method Detail

verify

boolean verify(byte[] data,
               int dataOffset,
               int dataLength,
               byte[] sig,
               int sigOffset,
               int sigLength)
               throws PublicKeyException

Verify a signature.

Parameters:

data - the data to be verified

dataOffset - offset into the data to begin verifying

dataLength - number of bytes to verify

sig - buffer containing the signature to be verified

sigOffset - offset of the signature in the buffer

sigLength - number of bytes in the signature

Returns:

true if the signature is valid

Throws:

PublicKeyException - if this isn't a proper public key, or the signature is malformed

verify

boolean verify(byte[] data,
               int dataOffset,
               int dataLength,
               byte[] sig)
               throws PublicKeyException

Verify a signature.

Parameters:

data - the data to be verified

dataOffset - offset into the data to begin verifying

dataLength - number of bytes to verify

sig - the signature to be verified

Returns:

true if the signature is valid

Throws:

PublicKeyException - if this isn't a proper public key, or the signature is malformed
