pem-iterator vs base64ct vs pem-rfc7468
Side-by-side comparison of Rust crates
42
pem-iterator
growingv0.2.0
Iterate over PEM-encoded data
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
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.
