List of encipher() Examples

Examples of encipher()

freenet.crypt.BlockCipher.encipher()
Enciphers the contents of block where block must be equal to getBlockSize()/8. The result is placed in result and, too has to have length getBlockSize()/8. Block and result may refer to the same array. Warning: It is not a guarantee that block will not be over- written in the course of the algorithm
freenet.crypt.PCFBMode.encipher()
Enciphers one byte of data, by XOR'ing the plaintext byte with one byte from the encrypted buffer. Then places the enciphered byte in the feedback register. If no bytes are available in the encrypted buffer, the feedback register is encrypted, providing block_size/8 new bytes for encryption
freenet.crypt.ciphers.Rijndael.encipher()

Examples of freenet.crypt.BlockCipher.encipher()

    IV[IV.length - 4] = (byte) (sequenceNumber >>> 24);
    IV[IV.length - 3] = (byte) (sequenceNumber >>> 16);
    IV[IV.length - 2] = (byte) (sequenceNumber >>> 8);
    IV[IV.length - 1] = (byte) (sequenceNumber);


    ivCipher.encipher(IV, IV);


    byte[] payload = Arrays.copyOfRange(buf, offset + hmacLength, offset + length);
    byte[] hash = Arrays.copyOfRange(buf, offset, offset + hmacLength);


    if(!HMAC.verifyWithSHA256(sessionKey.hmacKey, payload, hash)) return null;
