Struct Verifier 

pub struct Verifier { /* private fields */ }

Builder for verification operations.

Examples

Basic verification:

use libsignify_rs::{KeyGenerator, Signer, Verifier};
use tempfile::tempdir;
use std::fs;

let dir = tempdir()?;
let pub_path = dir.path().join("key.pub");
let sec_path = dir.path().join("key.sec");
let msg_path = dir.path().join("msg.txt");
let sig_path = dir.path().join("msg.sig");

// Setup
KeyGenerator::new().rounds(0).generate(&pub_path, &sec_path)?;
fs::write(&msg_path, "test message")?;
Signer::new().seckey(&sec_path).sign(&msg_path, &sig_path)?;

// Verify
Verifier::new()
    .pubkey(&pub_path)
    .quiet(true)
    .verify(&msg_path, &sig_path)?;

Embedded verification:

// Sign with embed
Signer::new()
    .seckey(&sec_path)
    .embed(true)
    .sign(&msg_path, &sig_path)?;

// Remove original message to verify extraction
fs::remove_file(&msg_path)?;

// Verify embedded
Verifier::new()
    .pubkey(&pub_path)
    .quiet(true)
    .embed(true)
    .verify(&msg_path, &sig_path)?;

Gzip verification:

// Sign gzip
Signer::new()
    .seckey(&sec_path)
    .gzip(true)
    .sign(&msg_path, &sig_path)?;

// Verify gzip
Verifier::new()
    .pubkey(&pub_path)
    .quiet(true)
    .gzip(true)
    .verify(&Path::new("-"), &sig_path)?; // Output to stdout (-) or file

Handling verification failures:

// Tamper with the message
fs::write(&msg_path, "tampered message")?;

// Verification should fail
let result = Verifier::new()
    .pubkey(&pub_path)
    .verify(&msg_path, &sig_path);

assert!(result.is_err());

Implementations

impl Verifier

pub fn new() -> Self

Create a new Verifier.

pub fn pubkey(self, path: impl Into<PathBuf>) -> Self

Set public key path.

pub fn quiet(self, quiet: bool) -> Self

Set quiet mode.

If true, suppresses “Signature Verified” output.

pub fn embed(self, embed: bool) -> Self

Set embed mode (signify -I).

Used when verifying an embedded signature.

pub fn gzip(self, gzip: bool) -> Self

Set gzip mode (signify -z).

Used when verifying a signed gzip archive.

pub fn verify(self, msg_path: &Path, sig_path: &Path) -> Result<()>

Verify a signature.

Errors

Returns errors if verification fails.

pub fn verify_io( self, msg_path: &Path, sig_path: &Path, msg_file: Option<File>, sig_file: Option<File>, pubkey_file: Option<File>, ) -> Result<()>

Verify with pre-opened resources.

Trait Implementations

impl Default for Verifier

fn default() -> Self

Returns the “default value” for a type.
