Crate essential_sign

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

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

Re-exports

pub use secp256k1;
