[NoKnowledge]

This claims to be well-documented and secure by default, but I cannot find a link to the documentation (or is it just the README)? What actual algorithm is used for encryption and for signing?

The README has a major red flag:

> From the math perspective, there is no difference between private and public keys, they both can be used to encrypt messages that only can de be decrypted by the other. Most of the security tools, including enc, artificially forbid using the public key for decrypting messages because that's not how it should be used (encrypting messages that anyone can decrypt is pointless).

Most security tools forbid that because it is dangerous! Also, this description sounds like textbook RSA is being used...
