RTEA 128/256 Symmetric Block Encryption Algorithm

RTEA (from Ruptor's TEA or Repaired TEA) - a symmetric block encryption algorithm used type "Feistel cipher", designed by Marcos el Ruptor, expansion TEA. Fixed some vulnerability in the algorithm. Like other variants of the algorithm TEA, the operation based on work with 32-bit numbers. The algorithm is much simpler and more productive XTEA, while, according to the authors and conducted by the developers according to statistical tests, is more resistant to cryptanalysis http://defectoscopy.comresults.html

Key size 128/256 bits
