INTRODUCTION: Blowfish‚ a symmetric block cipher developed by Bruce Schneier[SCHN93‚ SCHN94)‚ is a Feistel network‚ iterating simple encryption and decryption functions of 16 times each. The block size is 64 bits‚ and the key can be any length up to 448 bits. Although there is a complex initialization phase required before any encryption can take place‚ the actual encryption of data is very efficient on large microprocessors. Blowfish was designed to have the following characteristics: Fast:
