Webb7 aug. 2015 · Secret Key Cryptography. Most cryptography algorithms aren't as simple as hash functions. As a consequence, they are a lot more useful and can provide security guarantees beyond, "Yes, this output can be reproduced from this input." Consequently, they typically require two pieces of input: The message and a secret key. In cryptography, the Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code. It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop. The cipher is not subject to any patents.

Webb9 feb. 2024 · The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.
