Botan Crypto Library

Botan is a D library for crypto and TLS intended for vibe.d development/native compilation. It is a translation of the C++ library Botan, although the code is now in D and uses the memutils library as a replacement for the C++ STL. The commits are mirrored manually from C++ to D for future version invrements.

Current Version: 1.11.10 (git: 455bd2557cbb1343e59eefd97cb449f06a702c28)

Usage

Please consult the wiki for information on how to use this library.

Supported Algorithms

Botan supports a range of cryptographic algorithms and protocols, including:

TLS/Public Key Infrastructure

  • SSL/TLS (from SSL v3 to TLS v1.2), including using preshared keys (TLS-PSK) or passwords (TLS-SRP)
  • X.509 certificates (including generating new self-signed and CA certs) and CRLs
  • Certificate path validation and OCSP
  • PKCS #10 certificate requests (creation and certificate issue)

Public Key Cryptography

  • Encryption algorithms RSA, ElGamal, DLIES (padding schemes OAEP or PKCS #1 v1.5)
  • Signature algorithms RSA, DSA, ECDSA, GOST 34.10-2001, Nyberg-Rueppel, Rabin-Williams (padding schemes PSS, PKCS #1 v1.5, X9.31)
  • Key agreement techniques Diffie-Hellman and ECDH

Block ciphers

  • Authenticated cipher modes EAX, OCB, GCM, SIV, and CCM
  • Unauthenticated cipher modes CTR, CBC, XTS, CFB, OFB, and ECB
  • AES (including constant time SSSE3 and AES-NI versions)
  • AES candidates Serpent, Twofish, MARS, CAST-256, RC6
  • DES, 3DES and DESX
  • National/telecom block ciphers SEED, KASUMI, MISTY1, GOST 28147
  • Other block ciphers including Threefish-512, Blowfish, CAST-128, IDEA, Noekeon, TEA, XTEA, RC2, RC5, SAFER-SK
  • Large block cipher construction Lion

Stream Ciphers

  • RC4
  • Salsa20/XSalsa20
  • ChaCha20

Hash functions

  • SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512
  • RIPEMD-160, RIPEMD-128, Tiger, Whirlpool
  • SHA-3 winner Keccak-1600
  • SHA-3 candidate Skein-512
  • Hash function combiners (Parallel and Comb4P)
  • National standard hashes HAS-160 and GOST 34.11
  • Obsolete or insecure hashes MD5, MD4, MD2
  • Non-cryptographic checksums Adler32, CRC24, CRC32

Authentication Codes

  • HMAC
  • CMAC (aka OMAC1)
  • Obsolete designs CBC-MAC, ANSI X9.19 DES-MAC, and the protocol-specific SSLv3 authentication code

Other Useful Things

  • Key derivation functions for passwords, including PBKDF2
  • Password hashing functions, including bcrypt
  • General key derivation functions KDF1 and KDF2 from IEEE 1363
  • PRFs from ANSI X9.42, SSL v3.0, TLS v1.0

This section is by no means the last word on selecting which algorithms to use. However, botan includes a sometimes bewildering array of possible algorithms, and unless you're familiar with the latest developments in the field, it can be hard to know what is secure and what is not. The following attributes of the algorithms were evaluated when making this list: security, support by other implementations, patent/IP status, and efficiency (in roughly that order).

If your data is in motion, strongly consider using TLS v1.2 as a pre built, already standard and well studied protocol.

Otherwise, if you simply must do something custom, use:

  • Message encryption: AES or Serpent in EAX or GCM mode

  • General hash functions: SHA-256 or SHA-512

  • Message authentication: HMAC with SHA-256

  • Public Key Encryption: RSA, 2048+ bit keys, with OAEP and SHA-256 ("EME1(SHA-256)")

  • Public Key Signatures: RSA, 2048+ bit keys with PSS and SHA-512 ("EMSA4(SHA-512)"), or ECDSA with SHA-256 or SHA-512

  • Key Agreement: Diffie-Hellman or ECDH, with "KDF2(SHA-256)"

Issues

You can submit any issues in the github issue tracker. Any issue related to algorithms in the D library must also be submitted to the corresponding Botan C++ issue tracker.
