fi-verifiable-data
fi-verifiable-data library is focused on the representation and validation for Verifiable Credential and Verifiable Presentation. fi-digital-signatures crate is used to sign and verify VP and VC proofs. API documentation on docs.rs
Verifiable Credential
Rust
Sign

String::from("ESig"),

Verify
