 - [Botan: Crypto and TLS for Modern C++](https://botan.randombit.net/) A  C++ cryptographic library implementing a range of practical systems, such as TLS protocol, X.509 certificates, modern AEAD ciphers, PKCS#11 and TPM hardware support, password hashing, and post quantum crypto schemes. Several other language bindings are available, including Python. Versions of Botan that are approved by the BSI can be found on the [Github repository](https://github.com/Rohde-Schwarz/botan)
