base64ct vs pem-rfc7468 vs pkcs1
Side-by-side comparison of Rust crates
73
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
67
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.
61
pkcs1
growingv0.7.5
Pure Rust implementation of Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.2 (RFC 8017)
