🔐 go-krypto: A Go library collecting cryptographic algorithms designed in the Republic of Korea (SEED, ARIA, HIGHT, LEA, HAS160, LSH, KCDSA, EC-KCDSA)

A portable library implementing NIST SP 800-90A DRBGs

Fast CTR DRBG for x86 platforms.

Browser-based NIST SP 800-90A demo — HMAC_DRBG, CTR_DRBG, and Hash_DRBG with state visualizers, seeding, reseeding, and live NIST SP 800-22 statistical tests. The correct-case companion to Corrupted Oracle.

mplementation of "Improving the Imperceptibility of Pixel Value Difference and LSB Substitution Based Steganography Using Modulo Encoding" — a combined PVD + LSB + modulo encoding scheme with CTR_DRBG key-dependent embedding, including baseline comparisons and experiment framework.
