Enum DkimError 

pub enum DkimError {
    UnsupportedVersion,
    UnsupportedAlgorithm,
    UnsupportedCanonicalization,
    UnsupportedKeyType,
    BodyHashMismatch,
    AuidMismatch,
    PublicKeyRevoked,
    SignatureExpired,
    BodyLengthTag,
}

A DKIM1 specific failure, carried by Error::Dkim.

Produced while parsing a DKIM-Signature header or a _domainkey key record, and while verifying a signature.

Variants

UnsupportedVersion

The v= tag of the signature is not 1 (RFC 6376, Section 3.5).

UnsupportedAlgorithm

The a= tag names an algorithm this crate does not implement (supported: rsa-sha256, rsa-sha1 and ed25519-sha256).

UnsupportedCanonicalization

The c= tag names an unknown canonicalization algorithm.

UnsupportedKeyType

The k= tag of the key record names an unknown key type (supported: rsa and ed25519).

BodyHashMismatch

The body hash computed from the message does not match the bh= tag (RFC 6376, Section 6.1.3).

AuidMismatch

The domain of the i= tag is not d= or a subdomain of it, or the key record has t=s and the domains are not identical (RFC 6376, Section 3.5).

PublicKeyRevoked

The key record has an empty p= tag, meaning the key was revoked (RFC 6376, Section 3.6.1).

SignatureExpired

The x= expiration time has passed, or is not later than t= (RFC 6376, Section 3.5).

BodyLengthTag

An l= body length tag was present and strict parsing ignores such signatures, since content can be appended after the signed length.
