OpenSSL Example Code and Wrapper Functions

I have written some wrapper functions for the openssl library. These functions can serve as example code for using openssl. Download the code: myCryptoFunctions.tar.gz.

The following functions are contained in the tarball:

• Sign with a private key.
• Verify the signature with the corresponding public key.
• Encrypt with symmetric key.
• Decrypt with symmetric key.
• Generate an RSA public-private key pair.
• Save a public/private key to a buffer, load from the buffer.
• Generate random symmetric keys.
• Encrypt with a public key.
• MD5 and SHA hashes - both keyed and unkeyed.

If you find the code useful or find bugs, please do send me an email.
