Enum SubkeyChainError 

pub enum SubkeyChainError {
    BootstrapPubkeyDecode(String),
    BootstrapPubkeyLength(usize),
    BootstrapPubkeyInvalid(String),
    SignatureDecode(String),
    SignatureLength(usize),
    SubkeyPubkeyLength(usize),
    VerifyFailed,
    SelfReferential,
}

Errors produced by verify_subkey_chain.

Variants

BootstrapPubkeyDecode(String)

bootstrap_pubkey base64url decode failed.

BootstrapPubkeyLength(usize)

bootstrap_pubkey bytes were the wrong length (expect 33).

BootstrapPubkeyInvalid(String)

bootstrap_pubkey bytes do not parse as a valid P-256 point.

SignatureDecode(String)

subkey_binding_signature base64url decode failed.

SignatureLength(usize)

Signature bytes were the wrong length (expect 64).

SubkeyPubkeyLength(usize)

The supplied subkey_pubkey bytes were not 33 (compressed SEC1).

VerifyFailed

Signature did not verify against the binding message under the supplied bootstrap pubkey.

SelfReferential

Chain references a bootstrap pubkey identical to the subkey pubkey — self-referential chains are rejected because they do not prove continuity.

Trait Implementations

impl Debug for SubkeyChainError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SubkeyChainError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SubkeyChainError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
