essential-sign

Public key cryptography for the Essential ecosystem.

lib.rs:

A minimal crate providing Essential's generic signing, verification and public key recovery functions implemented using secp256k1 and the essential_hash crate.

Signing Arbitrary Data

For signing arbitrary data, the following take care of hashing the data in a consistent manner internally.

• sign
• verify
• recover

Signing Hashes

In cases where the Hash (or ContentAddress) is already known, the following are more efficient as they avoid hashing a second time:

• sign_hash
• verify_hash
• recover_hash
