go-openssl is a small library wrapping the crypto/aes functions in a way the output is compatible to OpenSSL / CryptoJS. For all encryption / decryption processes AES256 is used so this library will not be able to decrypt messages generated with other than openssl aes-256-cbc. If you’re using CryptoJS to process the data you also need to use AES256 on that side.
OpenSSL 1.1.0c compatibility
Starting with v2.0.0go-openssl generates the encryption keys using sha256sum algorithm. This is the default introduced in OpenSSL 1.1.0c. When encrypting data you can choose which digest method to use and therefore also continue to use md5sum. When decrypting OpenSSL encrypted data md5sum, sha1sum and sha256sum are supported.

The usage is quite simple as you don’t need any special knowledge about OpenSSL and/or AES256:
To execute the tests for this library you need to be on a system having /bin/bash and openssl available as the compatibility of the output is tested directly against the openssl binary. The library itself should be usable on all operating systems supported by Go and crypto/aes.
