Method Detail

addCertificate

public void addCertificate(X509Certificate x509)

getCertificates

public List<AgileEncryptionVerifier.AgileCertificateEntry> getCertificates()

clone

public AgileEncryptionVerifier clone()
                              throws CloneNotSupportedException

Overrides:

clone in class EncryptionVerifier

Throws:

CloneNotSupportedException

getKeySize

public int getKeySize()

The keysize (in bits) of the verifier data. This usually equals the keysize of the header, but only on a few exceptions, like files generated by Office for Mac, can be different.

Returns:

the keysize (in bits) of the verifier.

getBlockSize

public int getBlockSize()

The blockSize (in bytes) of the verifier data. This usually equals the blocksize of the header.

Returns:

the blockSize (in bytes) of the verifier,
