Release Notes

pyca/service-identity (service_identity)

v26.1.0

Compare Source

Added

• Python 3.14 and 3.15 are now officially supported.
  #​85
  #​93

Changed

• service-identity now uses cryptography's Rust-based ASN.1 decoder and doesn't depend on pyasn1 and pyasn1-modules anymore.
  As a result, the oldest supported pyOpenSSL backend combination is now pyOpenSSL 26.1.0 with cryptography 47.0.0.
  #​95

Fixed

• Verifying a single-label hostname (e.g. localhost) against a wildcard certificate pattern now raises VerificationError cleanly instead of crashing with an opaque ValueError.
  #​92
