Modern password hashing algorithms designed to resist brute-force attacks. Argon2 winner of Password Hashing Competition, bcrypt, scrypt, PBKDF2, and HKDF.
Derive secure keys with PBKDF2 online - the standard password-based key derivation defined in PKCS #5 and updated by RFC 8018. Generate strong encryption keys with configurable iterations for WiFi WPA and password storage.
Derive keys with Scrypt online - memory-hard password-based key derivation resisting GPU and ASIC attacks. Litecoin and Dogecoin mining algorithm, predecessor to Argon2 for password storage.
Calculate Argon2d hashes online - the data-dependent memory-hard variant maximizing GPU and ASIC resistance. For cryptocurrency proof-of-work and non-interactive hashing applications.
Hash passwords with Argon2i online - the side-channel resistant memory-hard variant for password storage. Data-independent memory access for secure cloud and shared environment deployments.
Hash passwords with Argon2id online - modern memory-hard password hashing and winner of the Password Hashing Competition. Designed to raise GPU and ASIC attack costs for password storage.
Hash passwords securely with bcrypt online - a widely deployed adaptive password hashing function since 1999. Compatible with PHP password_hash and configurable cost factors for long-term password storage.
Derive cryptographic keys with HKDF online - HMAC-based extract-and-expand key derivation (RFC 5869). Used in TLS 1.3, Signal Protocol, and IPsec for secure session key generation.
