Jhydro is a lightweight cryptographic library for Janet. It is a binding to libhydrogen, which can be found at https://github.com/jedisct1/libhydrogen. Jhydro is a direct binding to libhydrogen that supports cryptographic random number generation, hashing, symmetric key encryption, password hashing, key derivation functions, and public key signatures. These are all built using only a few built in primitives, which means that jhydro will not let you interact with other standard cryptographic formats such as SHA-256, AES, RSA, etc. Do not use jhydro if you want to implement SSL, for example. Jhydro will help you implement your own secure protocol over an insecure network, however.
