hpenc

Fast authenticated encryption CLI tool

Hpenc is a fast encryption command line tool with the following features: * Authenticated encryption - your data cannot be forged or corrupted without detection. * Parallel processing - hpenc uses block IO and you can process multiple blocks simultaneously, which is extremely useful if you have multi-core environment. * Strong ciphers - hpenc uses the state-of-art aes-gcm and chacha20 ciphers * Easy interface * Hardware acceleration - hpenc can utilize all its advanced cryptography functions defined for AES-NI and PCLMULQDQ instructions (that must be supported by openssl). For those with old or embedded CPU (such as ARM), hpenc provides portable and fast chacha20 cipher. * Simple key management * Secure random numbers generator - hpenc can work as pseudo-random numbers generator. In a set of standard tests (diehard) on the generated sequences hpenc generates secure sequences of pseudo-random numbers on a very high speed (gigabytes per second).
