base64ct vs noxtls-pem vs pem-rfc7468
Side-by-side comparison of Rust crates
71
base64ct
stablev1.8.3
Pure Rust implementation of Base64 (RFC 4648) which avoids any usages of data-dependent branches/LUTs and thereby provides portable "best effort" constant-time operation and embedded-friendly no_std support
53
noxtls-pem
experimentalv0.1.3
Internal implementation crate for noxtls: PEM encoding and decoding utilities.
66
pem-rfc7468
growingv1.0.0
PEM Encoding (RFC 7468) for PKIX, PKCS, and CMS Structures, implementing a strict subset of the original Privacy-Enhanced Mail encoding intended specifically for use with cryptographic keys, certificates, and other messages. Provides a no_std-friendly, constant-time implementation suitable for use with cryptographic private keys.
