@isomorphic-pgp/sign-and-verify
Currently it has some significant limitations that may make it unsuitable for many projects!
-
It does not check if a key has been revoked. The
verifyfunction will still return true if using a revoked key. - It only uses the Primary Key (the very first key in an OpenPGP message) and ignores the rest. The
verifyfunction will return false if the signature was made by a subkey and not the primary key. - It can only deal with RSA key types.
- It can only deal with detached binary signatures (signature type 0x00)
- It can't create signatures using private keys that are passphrase protected.
I will happily accept PRs to address these limitations as long as they respect the "keep the bundle size small" project goal.
