What this skill does
OpenSSL Secure Generation Generate cryptographically secure random data using openssl rand. Password/Secret Generation Common Lengths Use Case Command ---------- --------- Password (strong) openssl rand -base64 24 API key openssl rand -hex 32 Session token openssl rand -base64 48 Short PIN (8 digits) openssl rand -hex 4 xxd -r -p od -An -tu4 tr -d ' ' head -c 8 Notes -base64 outputs ~1.33x the byte count in characters -hex outputs 2x the byte count in characters Pipe through tr -dc to filter character sets Always use at least 16 bytes (128 bits) for secrets
