krypteia-arcana 0.1.0

Pure-Rust classical cryptographic primitives: RSA (PKCS#1 v1.5, OAEP), ECC (NIST P-256/384/521, secp256k1), ECDSA, EdDSA (Ed25519), X25519, AES (128/192/256, GCM/CBC), DES/3DES, SHA-1/2/3, HMAC. Side-channel-aware (Montgomery ladder, branchless point_add_ct). Targets embedded (no_std), STM32 M0/M4/M33, ESP32-C3 RISC-V. Zero runtime dependencies.
