Hi,

I am going to install OpenSSL and I am using amazon AWS.

What codes in OpenSSL can I use for the following:

1. Encode/decode with base64

2. Encrypt a file and decrypt a file using DES or AES with passwords

3. Generate RSA/DSA private key/public key pairs

4. Encrypt/decrypt using RSA

5. Digitally sign a file using DSA

6. Generate a self-signed certificate
