Struct ssb_crypto::Signature

#[repr(C)]pub struct Signature(pub [u8; 64]);

A cryptographic signature of some content, generated by Keypair::sign and verified by PublicKey::verify.

Implementations

impl Signature

pub const SIZE: usize

Size of a signature, in bytes (== 64).

pub fn from_slice(s: &[u8]) -> Option<Self>

Deserialize a signature from a byte slice. The slice length must be 64.

pub fn from_base64(s: &str) -> Option<Self>

Deserialize a signature from a base-64 encoded string. Ignores optional .sig.ed25519 suffix.

Example

use ssb_crypto::Signature;
let s = "QTsCZ+INzDENs1dAdej14Lsp1v2UCXUtRZBv4HlDGo6WZn29ZYM5lZtxnyNC53LxX0ucY1x8NlC1A1RjY7FHBA==.sig.ed25519";
let sig = Signature::from_base64(s).unwrap();
