Cryptopp

Features

Public Key Cryptography - An implementation of RSA, ECC, DSA, and other public-key algorithms for secure key exchange and digital signatures.
Data Processing Pipelines - Processes data through composable stream objects that transform data in stages via sources, filters, and sinks.
Cryptographic Algorithm Selection - Uses C++ templates to select cryptographic algorithms at compile time, enabling zero-cost abstractions and compile-time polymorphism.
Integrity Checking Libraries - Computing message digests or HMACs to detect accidental or malicious changes to files, packets, or stored data.
Cryptographic Hash Verifiers - Hash any input to produce a fixed-size digest for verifying data integrity and authenticating messages.
Cryptographic Primitives - Writing or integrating low-level building blocks such as block ciphers, hash functions, and public key algorithms into a larger application.
Digital Signatures - Signing documents or verifying signatures to confirm the authenticity and integrity of data from a known sender.
Asymmetric Encryption - Encrypt data or exchange keys using a public-private key pair without a shared secret.
Key Agreement Protocols - Establishing a shared secret between two parties over an untrusted network using protocols such as Diffie-Hellman or ECDH.
Symmetric Cipher Implementations - A library providing block ciphers, stream ciphers, and hash functions for data integrity and confidentiality.
Symmetric Encryption - Encrypt plaintext into ciphertext using a shared secret key for data confidentiality and private communication.
Compile-Time Cryptographic Parameter Configurators - Configures encryption parameters such as key size and mode using template arguments to eliminate runtime overhead.
Secure Memory Allocators - Overrides allocation and deallocation to provide securely wiped memory buffers that prevent sensitive data leakage.
Static Cryptographic Factory Registries - Registers algorithm classes by name in a static factory, allowing runtime lookup and instantiation of cryptographic primitives.
Authenticated Encryption - Encrypting data while simultaneously verifying its integrity and authenticity using algorithms like GCM or CCM.
Cryptographic Toolkits - A cross-platform set of cryptographic classes that work on various operating systems without modification.
Invertible Cryptographic Transform Frameworks - Defines base classes for both directions of cryptographic transformations, ensuring symmetric interfaces for encryption and decryption pairs.

phpseclib is a pure-PHP cryptographic library that provides a comprehensive suite of cryptographic operations entirely without requiring compiled C extensions. At its core, it implements arbitrary-precision integer arithmetic for big-number math, ASN.1 DER encoding and decoding for working with cryptographic data structures, and a full set of pure-PHP cryptographic primitives. The library is designed to operate on PHP 5.6 and above, automatically detecting and using native extensions like GMP or BCMath when available, but falling back to its own pure-PHP implementations when they are not.
