Perl extension to Tiny Encryption Algorithm
TEA is a 64-bit symmetric block cipher with a 128-bit key and a variable number of rounds 32 is recommended. It has a low setup time, and depends on a large number of rounds for security, rather than a complex algorithm. It was developed by David J. Wheeler and Roger M. Needham, and is described at http//www.ftp.cl.cam.ac.uk/ftp/papers/djw-rmn/djw-rmn-tea.html .
