Note: The Python Cryptographic Authority strongly suggests the use of pyca/cryptography where possible. If you are using pyOpenSSL for anything other than making a TLS connection you should move to cryptography and drop your pyOpenSSL dependency.
High-level wrapper around a subset of the OpenSSL library. Includes

- Extensive error-handling mechanism, mirroring OpenSSL's error codes
... and much more.
