base32ct vs aws-lc-rs vs p256

Side-by-side comparison of Rust crates

69
base32ct
growingv0.3.1

Pure Rust implementation of Base32 (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

81
aws-lc-rs
stablev1.16.2

aws-lc-rs is a cryptographic library using AWS-LC for its cryptographic operations. This library strives to be API-compatible with the popular Rust library named ring.

77
p256
growingv0.13.2

Pure Rust implementation of the NIST P-256 (a.k.a. secp256r1, prime256v1) elliptic curve as defined in SP 800-186, with support for ECDH, ECDSA signing/verification, and general purpose curve arithmetic
