Struct yaca::VerifyContext

pub struct VerifyContext { /* fields omitted */ }

Context for Verify operations

Implementations

impl VerifyContext

pub fn initialize(
    algo: &DigestAlgorithm,
    pub_key: &Key
) -> Result<VerifyContext>

Initializes a signature verification context for asymmetric signatures

• algo is a digest algorithm used to calculate the signature
• pub_key is a matching public key to the one used to calculate the signature, algorithm is deduced based on key type, supported key types:
  • KeyType::RsaPublic,
  • KeyType::DsaPublic,
  • KeyType::EcPublic.
• For RSA operations the default padding used is Padding::Pkcs1. It can be changed using CtxPad::set_property_padding(). For verify to succeed it has to be set to the same value it was signed with.

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

Feeds the message into the digital signature verification algorithm

• message is a chunk of data used to calculate the signature from.

pub fn finalize(&self, signature: &[u8]) -> Result<bool>

Performs the verification

• signature is a message signature to be verified.
• Returns true in case of a successful verification, false otherwise.
