Botan — Japanese for peony flower — is an open source cryptography library, and is commonly used with AWS. It normally integrates with C, C++, and Python, but can integrate with most languages. It is available on this GitHub [here]. The supported symmetric key methods are AES, Blowfish, CAST, DES, TripleDES, GOST, IDEA, Noekeon, SHACAL2, SM4, Serpent, ThreeFish, TwoFish, ChaCha20, RC4, and Sala20:
