A D library for crypto and TLS
To use this package, put the following dependency into your project's dependencies section:
Botan Crypto Library
Botan is a very complete crypto powerhouse packaged in a D library.
Current Version: v1.11.10, commit ref# 3e55885d20c1a579df13be3470491e5c378a2688
A TLS client/server with ALPN, SNI and HTTP/2 has been added to the http2-botan vibe.d branch on my fork.
Botan has been tested on Windows x86, Windows x64, OSX x64, Linux x86, Linux x64 with DMD v2.067, v2.067.1, v2.068.
For development, you should use the Mono-D IDE, as it has been specifically crafted to handle the high amount of symbols.
Install DMD v2.067.0+
Install dub v0.9.22+
Compile Botan tests using
dub test --arch=x86_64for x64, or
dub test --arch=x86for x86. On Windows 64 bit, you will need to compile DMD64 using the Microsoft Visual Studio solution (.sln) in the DMD src/ folder. On Windows 32bit (--arch=x86), you will need to use the microsoft linker (mscoff):
dub test --config=32mscoff, and DMD 2.068 (currently git master).
For further information, start with the GitHub Wiki for information on how to use this library.

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
- 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
- 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
- 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)"
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.
