Method Detail

init

public void init(java.security.PublicKey pubkey,
        java.security.PrivateKey prvkey)

Description copied from interface: Signature

Initialize this signature with the given public key and private key. If the private key is null, only signature verification can be performed.

Specified by:

init in interface Signature

Parameters:

pubkey - (null-ok) specify in case verification is needed

prvkey - (null-ok) specify in case signing is needed

update

public void update(byte[] H)

Description copied from interface: Signature

Convenience method, same as calling Signature.update(byte[], int, int) with offset as 0 and H.length.

Specified by:

update in interface Signature

Parameters:

H - the byte-array to update with

update

public void update(byte[] H,
          int off,
          int len)

Description copied from interface: Signature

Update the computed signature with the given data.

Specified by:

update in interface Signature

Parameters:

H - byte-array to update with

off - offset within the array

len - length until which to compute

sign

public byte[] sign()

Description copied from interface: Signature

Compute the signature.

Specified by:

sign in interface Signature

Returns:

the computed signature

encode

public byte[] encode(byte[] signature)

Description copied from interface: Signature

Encode the signature as blog

Specified by:

encode in interface Signature

Parameters:

signature - the signature to encode

Returns:

Encoded signature

verify

public boolean verify(byte[] sig)

Description copied from interface: Signature

Verify against the given signature.

Specified by:

verify in interface Signature

Parameters:

sig - the signature to verify against

Returns:

true on successful verification, false on failure
