`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. `go-openssl` is a small library wrapping the `crypto/aes` functions in a way the output is compatible to OpenSSL / CryptoJS.

## OpenSSL 1.1.0
With the release of OpenSSL 1.1.0c the default hashing algorithm [changed from `md5` to `sha256`](https://www.cryptopp.com/wiki/OPENSSL_EVP_BytesToKey). Using this new default breaks the en- and decryption used in this library. Currently you need to specify to use `md5` hashing when encrypting using `openssl enc -aes-256-cbc -a -k yourpassword -md md5`. Sadly using `sha256` is not a drop-in replacement and therefore needs to be implemented as a separate function following the OpenSSL source code.
