    cppcrypto

    C++ cryptographic library (modern hash functions, ciphers, KDFs)

    cppcrypto provides optimized implementations of cryptographic primitives. Hash functions: BLAKE, BLAKE2, Echo, Esch, Groestl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, SHAKE, Skein, SM3, Streebog, Whirlpool. Block ciphers: Anubis, Aria, Camellia, CAST-256, Kalyna, Kuznyechik, Mars, Serpent, Simon, SM4, Speck, Threefish, Twofish, and Rijndael (AES) with all block/key sizes. Stream ciphers: HC-128, HC-256, Salsa20, XSalsa20, ChaCha, XChaCha. Encryption modes: CBC, CTR. AEAD modes: Encrypt-then-MAC (EtM), GCM, OCB, ChaCha-Poly1305, Schwaemm. Streaming AEAD. MAC functions: HMAC, Poly1305. Key derivation functions: PBKDF2, scrypt, Argon2, HKDF. Includes sample command-line tools: - 'digest' - for calculating and verifying file checksum(s) using any of the supported hash algorithms (similar to md5sum or RHash). - 'cryptor' - for file encryption using Serpent-256 algorithm in AEAD mode. Check out the cppcrypto web site linked below for programming documentation.

    AnCH Framework

    AnCH Framework

    Another C++ Hack

    This project has been migrated to GitHub : https://github.com/vlachenal/anch-framework AnCH framework aims to provide utility classes for some common programming features. Features are implemented to be used as simply as possible. This framework was initially a way to test new C++ specifications (C++11) and to test C++ design patterns and tricks. Only POSIX systems are supported for now. Others could be supported later. (Partial) Doxygen documentation can be found on project home page.

    A kind of encryption named "simple stream encrypt". The length of plaintext segment or the length of key is not limited, but must greater than zero. The lengths of every plaintext segment in a process don't require equivalency.

    Tink

    Tink

    A library that provides cryptographic APIs that are easy and secure

    Tink is a multi-language, cross-platform, open source library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse. Tink is an open-source cryptography library written by cryptographers and security engineers at Google. Tink's secure and simple APIs reduce common pitfalls through user-centered design, careful implementation and code reviews, and extensive testing. Tink helps users without a cryptography background safely implement common cryptographic tasks. At Google, Tink has been deployed in hundreds of products and systems. Cryptography is difficult to get right. With Tink, you can encrypt or sign data with just a few lines of code, with built-in security guarantees to help you avoid pitfalls. Tink adds security protections on top of well known libraries like BoringSSL and Java Cryptography Architecture and shows them right in the interfaces, so auditors and tools can quickly find gaps.
