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 … Visa mer TEA operates on two 32-bit unsigned integers (could be derived from a 64-bit data block) and uses a 128-bit key. It has a Feistel structure with a suggested 64 rounds, typically implemented in pairs termed cycles. It has … Visa mer Following is an adaptation of the reference encryption and decryption routines in C, released into the public domain by David Wheeler and Roger … Visa mer 1. ^ Matthew D. Russell (27 February 2004). "Tinyness: An Overview of TEA and Related Ciphers". Archived from the original on 12 August 2007. 2. ^ Kelsey, John; Visa mer The first published version of TEA was supplemented by a second version that incorporated extensions to make it more secure. Block TEA (which was specified along with XTEA) operates on arbitrary-size blocks in place of the 64-bit blocks of the original. Visa mer • RC4 – A stream cipher that, just like TEA, is designed to be very simple to implement. • XTEA – First version of Block TEA's successor. • XXTEA – Corrected Block TEA's successor.

There's a variant of it called "Block TEA" which allows multiple blocks or words but still uses a 64 bit block size (I may be wrong at this). So I am confused about how nOFB can work alongside TEA to encrypt any text data.

In cryptography, XTEA (eXtended TEA) is a block cipher designed to correct weaknesses in TEA.
