    SymPy

    SymPy

    A computer algebra system written in pure Python

    SymPy is an open source Python library for symbolic mathematics. Its goal is to become a full-featured computer algebra system (CAS) while maintaining the simplicity of its code. Written entirely in Python, SymPy is easy to use, comprehensible and easily extensible. It’s also very lightweight as it solely depends on mpmath, a pure Python library for arbitrary floating point arithmetic. SymPy has participated in every Google Summer of Code since 2007 and because of this has continuously...

    Microsoft SEAL

    Easy-to-use and powerful homomorphic encryption library

    Microsoft SEAL is an open-source homomorphic encryption library that allows computations to be performed directly on encrypted data, with no need for any decryption. Developed by the Cryptography and Privacy Research group at Microsoft, it enables software engineers to build end-to-end encrypted data storage and computation services that never have to procure the customer's key. Microsoft SEAL is very easy to use, compile and run in many different environments. Homomorphic encryption is an encryption scheme that allows the cloud to compute directly on the encrypted data, without requiring the data to be decrypted first. ...

    pgsodium

    pgsodium

    Modern cryptography for PostgreSQL using libsodium

    pgsodium is an encryption library extension for PostgreSQL using the libsodium library for high-level cryptographic algorithms. pgsodium can be used a straight interface to libsodium, but it can also use a powerful feature called Server Key Management where pgsodium loads an external secret key into memory that is never accessible to SQL. This inaccessible root key can then be used to derive sub-keys and keypairs by key id. This id (type bigint) can then be stored instead of the derived key.
