base64-ng 1.0.0

[eldryoth]

base64-ng 1.0.0

First stable release of base64-ng.

Highlights

• Stable strict RFC 4648 Base64 API with standard, URL-safe, MIME, PEM, bcrypt, crypt, and custom alphabet support
• Zero runtime dependencies in the core crate
• no_std support with optional alloc, std, and stream features
• Strict canonical decoding by default, with explicit legacy/whitespace-tolerant APIs
• Allocation-free slice APIs, stack-backed buffers, and in-place decode support
• Constant-time-oriented decoding APIs for sensitive inputs, with clear-tail variants for failure-safe buffer handling
• Best-effort volatile wiping for internal secret buffers and stream staging buffers
• Streaming std::io encoder/decoder adapters
• Release-gated security evidence: fuzz harnesses, dudect harness, Miri-compatible tests, cargo-audit/cargo-deny checks, no-alloc smoke tests, and cross-target checks
• Scalar-only backend for 1.0.0; SIMD remains behind documented admission evidence for future releases

Notes

Kani/formal verification remains planned for a future 1.0.x assurance release once toolchain support is suitable. The constant-time and zeroization APIs are documented as best-effort Rust implementations, not formal hardware-level guarantees.
