rust-openssl
Safe, idiomatic Rust bindings to OpenSSL
libsodium-wrappers
WebAssembly build of libsodium with hand-friendly JavaScript wrappers for encryption, signing, hashing, and key exchange.
bytemuck
A zero-cost, no_std Rust crate for safely casting between plain data types and reinterpreting slices as bytes.
serde_with
Custom de/serialization helpers for Rust's serde, via the with and serde_as annotations
zeroize

GoGo Protobuf
A deprecated fork of golang/protobuf adding faster marshaling, custom types, and richer Go code generation for Protocol Buffers.
image-spec
Canonical Go types and embedded JSON Schema validation for the OCI Image Format specification.
lz-string
Fast, dependency-free LZ-based string compression for JavaScript and TypeScript
feedparser
Parses RSS, Atom, RDF, CDF, and JSON feeds into one normalized Python dictionary.
jsonschema

base64-js
Pure JavaScript base64 encoding and decoding for byte arrays, with no native dependencies.
base-64
A lightweight, RFC 4648-compliant base64 encoder and decoder for JavaScript, fully compatible with atob() and btoa().
Partial JSON
Parses incomplete JSON strings streamed token-by-token from an LLM into usable JavaScript values as they arrive.
md5
A small, dependency-free Rust implementation of the MD5 hash function
pyasn1
Pure-Python implementation of ASN.1 types with BER, CER, and DER serialization codecs.
