Cipher block chaining decryptionMatthew M. Bace
a ciphertext block affects the decryption of all subsequent blocks. Rearrangement of the order of the ciphertext blocks causes with this decryption to become corrupted. Basically, in cipher block chaining, each plaintext block is XORed (see XOR) with the immediately previous ciphertext block and ...
One of CBC's key characteristics is its use of a chaining process that causes the decryption of a block ofciphertextto depend on all the preceding ciphertext blocks. As a result, the entire validity of all preceding blocks is contained in the previous, adjacent ciphertext block. A single b...
Cryptography - Block Cipher - Block ciphers and stream ciphers are the two categories into which encryption techniques divide according to the way the input is handled. A block cipher creates a ciphertext the same size by operating on fixed-size input bl
The http://faq.javaranch.com/java/SecurityFaq links to a complete example of encryption/decryption with JCE. You'll just need to adjust the Cipher and SecretKeyFactory instances as appropriate for your needs (e.g. "DESede" for TripleDES). I'm not sure what you mean by "3 different ke...

I have a use case where I’m encrypting in the JavaScript code and decrypting in the Java code using AES/CBC/PKCS5Padding algorithm. I’m generating a random IV in the JavaScript code and sending along with the ciphertext, which I’m parsing in Java and passing to Decryption. ...
