phpseclib is designed to be ultra-portable. The 3.0 version works on PHP 5.6+ and doesn't require any extensions. For purposes of speed, OpenSSL, GMP, libsodium or mcrypt are used, if they're available, but they are not required. phpseclib is designed to be fully interoperable with standardized cryptography libraries and protocols. MIT-licensed pure-PHP implementations of SSH-2, SFTP, X.509, an arbitrary-precision integer arithmetic library, Ed25519 / Ed449 / Curve25519 / Curve449, ECDSA / ECDH...

AVR128DA /Atmega128 microcontroller based open source EID smartcard with RSA (512-2048) and ECC (prime192v1, prime256v1, secp384r1, secp521r1 and secp256k1) support. Compatible with MyEID card from Aventra. Supported in windows and linux by opensc package. Allow about 64KiB space for keys/certificates. PKCS#15 structure supported. USB token with CCID interface based on xmega128a4u with same features as card. High speed AVR multiple precision arithmetic: squaring, multiplication, exponentiation.

A large integer arithmetic library written in plain C.

With BinaryCrypt, you can convert between regular text, binary, hexadecimal, octal decimal and decimal. You can convert only decimal (as of right now) to any base up to base 64. You can also save your converted text to a file or open a converted text file to decrypt the message, and perform basic arithmetic in binary. The git repo for the C# code is located at: https://github.com/m1r4g3/BinaryCrypt-.Net

... lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. MOTE alternates its shift and rotation constants unpredictably, and has passed the most stringent industry-standard tests for randomness and security, including NIST & DIEHARD.

MathX is a fixed-length arithmetic-types written in pure c++ templates. The goal is to provide signed-integer, unsigned-integer, IEEE-754 float-point and fixed-point types, all with specific number of bits. To this moment, only signed-integer and unsigned-integer are completed for little-endain architecture. Any compiler that support c++03 or c++11 can successfully compile MathX. Refer to README for more information.

The Safe Math Library is a set of APIs designed to help mitigate the risk of arithmetic overflows. This library is modeled after ISO/IEC TR 24731.

Pure-Java cryptographic calculator, featuring basic arithmetic operators, cryptographic operations, multiple key file formats and edition of ASN.1 object files.

K is a C++ library featuring Genetic Programming, cryptography, 64 bits arithmetic, cross-platform macros and unicode conversion routines. It compiles on NewtonOS, Mac < X, Unix and Windows and it makes little use of C++ templates.
