PowerCrp is an add-on library for cryptography application development in Xbase++.

PowerCrp library contains functions which implement a wide range of cryptographic algorithms used in various Internet standards. Their functionalities include cryptographic hash functions, message authentication codes (MAC), key derivation functions (KDF), one-time passwords (OTP), symmetric encryption, public and private key cryptography, key exchange, certificate and certificate store management, public key cryptography standards (PKCS) structures, and various utilities.

PowerCrp functions encapsulate most of the functionalities of various cryptographic standards, which are defined as function parameters. The functions are generalized and automated. You don't need to know cryptography and its various algorithms and systems. Instead, use PowerCrp functions as building blocks to create short, fast and efficient programs.

PowerCrp library supports Alaska Xbase++ V.1.8 to V.2.0.
