* It includes a various cryptographic algorithms, formats, and protocols such as SSL and TLS. * It provides useful tools such TLS, X.509 certificates, ECDSA, AES, GCM, ChaCha20Poly1305, and bcrypt. * Include variety crypto algorithms of different uses. * The library can also be built into a single-file amalgamation for easy inclusion into external build systems. * In addition to C++, botan has a C89 API specifically designed to be easy to call from other languages. A Python binding using ctypes is included.

It supply variety of functions for all cryptograhic kinds such as symmetric ciphers (AES, DES, Blowfish, CAST5, Twofish, Arcfour), hash algorithms (MD4, MD5, RIPE-MD160, SHA-1, TIGER-192), MACs (HMAC for all hash algorithms), public key algorithms (RSA, ElGamal, DSA), large integer functions, random numbers and a lot of supporting functions. * Libgcrypt works on most POSIX systems and many pre-POSIX systems. * It can also be built using a cross-compiler system for Microsoft Windows.
