Heimdal crypto library

1.1

Introduction

Heimdal libhcrypto library is a implementation many crypto algorithms, among others: AES, SHA, DES, RSA, Camellia and many help function.

hcrypto provies a OpenSSL compatible interface libcrypto interface and is licensed under a 3 clause BSD license (GPL compatible).

The project web page: http://www.h5l.org/

Sections of this manual:

• EVP - generic crypto interface
• DH - Diffie-Hellman key exchange
• RSA - public-key cryptography

Control functions

Functions controlling general behavior, like adding algorithms, are documented in this module: hcrypto function controlling behavior .

Return values

Return values are diffrent in this module to be compatible with OpenSSL interface. The diffrence is that on success 1 is returned instead of the customary 0.
