RUSTSEC-2025-0134

The rustls-pemfile crate is no longer maintained. The repository has been archived since August 2025, and users are encouraged to depend directly on the underlying PEM parsing code included in rustls-pki-types since 1.9.0. The latest version of rustls-pemfile is in fact a thin wrapper around the same code used in rustls-pki-types, so migrating should be straightforward.

The new API is represented by the PemObject trait, which provides methods for reading a single or multiple PEM objects from a file or byte slice.
