Struct UnparsedPublicKey 

pub struct UnparsedPublicKey<B: AsRef<[u8]>> { /* private fields */ }

An unparsed, possibly malformed, public key for signature verification.

Implementations

impl<B: AsRef<[u8]>> UnparsedPublicKey<B>

pub fn new(algorithm: &'static dyn VerificationAlgorithm, bytes: B) -> Self

Construct a new UnparsedPublicKey.

No validation of bytes is done until verify() is called.

pub fn verify( &self, message: &[u8], signature: &[u8], ) -> Result<(), Unspecified>

Parses the public key and verifies signature is a valid signature of message using it.

See the crate::signature module-level documentation for examples.

Errors

error::Unspecified if inputs not verified.

pub fn verify_digest( &self, digest: &Digest, signature: &[u8], ) -> Result<(), Unspecified>

Parses the public key and verifies signature is a valid signature of digest using it.

See the crate::signature module-level documentation for examples.

Errors

error::Unspecified if inputs not verified.

pub fn parse(&self) -> Result<ParsedPublicKey, KeyRejected>

Parses the public key bytes and returns a ParsedPublicKey.

This method validates the public key format and creates a ParsedPublicKey that can be used for more efficient signature verification operations. The parsing overhead is incurred once, making subsequent verifications faster compared to using UnparsedPublicKey::verify directly.

This is equivalent to calling ParsedPublicKey::new with the same algorithm and bytes.

Errors

KeyRejected if the public key bytes are malformed or incompatible with the specified algorithm.
