b64ct vs base64ct vs data-encoding
Side-by-side comparison of Rust crates
41
b64ct
growingv0.2.0
Pure Rust implementation of B64, a subset of the standard Base64 encoding (RFC 4648) used by the PHC string format. Implemented without data-dependent branches or lookup tables providing "best effort" constant-time operation.
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
73
data-encoding
stablev2.10.0
Efficient and customizable data-encoding functions like base64, base32, and hex
