Method Detail

setSalt

public void setSalt(byte[] salt)

Overrides:

setSalt in class EncryptionVerifier

setEncryptedVerifier

public void setEncryptedVerifier(byte[] encryptedVerifier)

Overrides:

setEncryptedVerifier in class EncryptionVerifier

setEncryptedVerifierHash

public void setEncryptedVerifierHash(byte[] encryptedVerifierHash)

Overrides:

setEncryptedVerifierHash in class EncryptionVerifier

setEncryptedKey

public void setEncryptedKey(byte[] encryptedKey)

copy

public AgileEncryptionVerifier copy()

Specified by:

copy in interface Duplicatable

Specified by:

copy in class EncryptionVerifier

Returns:

a deep copy of the implementing class / instance

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,

setKeySize

public void setKeySize(int keyBits)

Sets the keysize (in bits) of the verifier

Parameters:

keyBits - the keysize (in bits)

setBlockSize

public void setBlockSize(int blockSize)

Sets the blockSize (in bytes) of the verifier

Parameters:

blockSize - the blockSize (in bytes)

setCipherAlgorithm

public final void setCipherAlgorithm(CipherAlgorithm cipherAlgorithm)

Overrides:

setCipherAlgorithm in class EncryptionVerifier
