Hi!
I'm new to openssl.
I've got two questions on EVP API:
1. What do EVP_EncryptInit_ex and EVP_CipherInit_ex differ with?
When should I use encrypt/decrypt and when cipher?
2. Where can I read about cipher modes?
  There are several modes for each cipher on
   http://openssl.org/docs/crypto/EVP_EncryptInit.html#CIPHER%20LISTING
  They differ with suffix like _cbc, _ecb, _cfb, _ofb and etc.
What are meanings of these suffixes and use-cases?

Best regards,
Alexey Luchko.
