Module identity 

SIP authenticated identity and PASSporT (RFC 8224 and RFC 8225).

This module is deliberately sans-I/O: callers supply time and keys. Credential retrieval, trust policy, and authorization belong to the user-agent layer.

Structs

Es256SigningKey

An ES256 private key. Its debug form never includes key material.

Es256VerifyingKey

An ES256 public key.

IdentityHeader

A parsed RFC 8224 Identity header value.

Enums

CanonicalIdentity

A canonical origin or destination identity.

IdentityError

A PASSporT construction or verification failure.

Functions

date_from_timestamp

Format Unix seconds as the one GMT date form SIP permits.

date_timestamp

Parse one already syntax-checked SIP Date into Unix seconds.

passport_issued_at

Read iat from a full PASSporT; a compact form carries none to read.

Canonical From and To identities from one SIP request.

sign_passport

Construct and deterministically sign a full baseline PASSporT.

verify_passport

Verify a full or compact baseline PASSporT against SIP-derived claims.
