Secure Password & Passphrase Generator
Generate high-entropy random passwords and multi-word passphrases with entropy score analysis.
Password Strength & Entropy Checker
Analyze password security strength, estimate brute-force crack time across GPU clusters, detect vulnerable patterns, and calculate Shannon and theoretical bit entropy.
Random PIN Code Generator
Generate cryptographically secure 4-digit, 6-digit, 8-digit, or custom-length numeric PIN codes with anti-sequential filtering and bulk batch export.
Random API Token & Secret Generator
Generate cryptographically secure API keys, bearer tokens, hex secrets, NanoIDs, and URL-safe strings with customizable prefixes, length, and batch export.
HMAC Generator & Signature Signer
Generate and verify keyed-hash message authentication codes (HMAC-SHA256, SHA-512, MD5) for API webhooks, Stripe, GitHub, and AWS.
Bcrypt Generator & Password Hash Verifier
Generate salted bcrypt password hashes ($2b$, $2a$, $2y$) with configurable cost rounds (4–16) and verify plaintext passwords against hashes.
Hash Type Identifier & Analyzer
Instantly identify unknown cryptographic hashes, password crypt formats, Hashcat modes, John the Ripper formats, and security ratings.
SSL & X.509 Certificate Decoder
Decode and inspect SSL/TLS and X.509 certificates in PEM or DER format. Analyze subject domains, SANs, CA issuer chain, validity countdown, key length, and SHA-256 fingerprints with zero server uploads.
CSR Decoder & Certificate Request Validator
Decode and inspect PKCS#10 Certificate Signing Requests (CSR). Verify Common Name, SAN domains, organization attributes, key size, signature algorithm, and CA pre-flight compliance before SSL procurement.
SSL Certificate Converter (PEM ⇄ DER)
Convert SSL/TLS certificates and keys between ASCII PEM and binary DER formats. Download converted .der files or copy armored PEM text with RFC 7468 line wrapping and custom headers.
Secret & API Key Leak Detector
Scan source code, .env files, configuration, and logs for accidentally leaked secrets, tokens, private keys, and API credentials (AWS, OpenAI, GitHub, Stripe, Slack, GCP, Database URIs) with 100% in-browser offline scanning and one-click sanitization.
