Go-File-Encryption
Introduction
- A file encryption/decryption library that uses the same algorithm as OpenSSL's with IV and salt
- You can set key and IV manually instead of creating them from password and salt.
!!!Caution!!!
- OpenSSL's key creation algorithm with password and salt is NOT secure.
- You should set key and IV manually or use some alternative algorithms.
Examples
- Read cbc_test.go
