for contributes and fix
A small part of this work is inspired on MySSL, interface to OpenSSL for
Delphi written by Jan Tomasek.

== Changelog =======================================================
Version 0.7n, 2010-12-27
- typo corrected
Version 0.7m, 2010-11-05
- added support for PCKS#8 functions (contributed by Luis Carrasco - Bambu Code, Mexico),
- redefinition of PChar as PCharacter to handle PChar and PAnsiChar types
- basic AES support
Version 0.7h, 2009-02-25
- added X509_sign(),
Version 0.7g, 2007-02-20
- Bugfix: PKCS12_parse function uses a by-reference parameter
- Bugfix: BIO_get_mem_data(). Thanks to Andrei
- Removed redundant declarations
Version 0.7f, 2007-02-20
- Bugfix: PEM_read_* function uses a by-reference parameter
Version 0.7e, 2007-02-11
- Bugfix
- Replace BN_mod import with a wrapper to BN_div, see man BN_mul(3)
Version 0.7d, 2006-12-15
- Typos
- Removed EVP_MD_size and EVP_MD_CTX_size: these functions are not defined in
DLL and handle their parameter in a non-opaque way.
Version 0.7c, 2006-11-14
- Add BIGNUM functions
- Defined RSA record
- Add missing EVP_VerifyFinal
Version 0.7b, 2006-11-05
- Between 0.9.6h and 0.9.7, OpenSSL split OpenSSL_add_all_algorithms
in two new functions. Some versions of libeay32.dll use old name,
some use new one. See http://www.openssl.org/news/changelog.html
In this unit, OpenSSL_add_all_algorithms is now a wrapper that
dynamically loads appropriate function from DLL.
Version 0.7a, 2006-09-14
- Bug fixes
- Defined wrapper for OpenSSL memory management function
