Security & Hashing Tools Page
Cryptographic hash generators, password tools, and security utilities for data protection.
Argon2 Hash Generator & Verifier
Generate secure Argon2 hashes and verify passwords against existing hashes. Argon2 is the winner of the Password Hashing Competition and recommended for new applications with configurable memory, time, and parallelism parameters.
Bcrypt Hash Generator & Verifier
Generate secure bcrypt hashes and verify passwords against existing hashes. Bcrypt is a password hashing function with built-in salt and configurable cost factor for enhanced security.
Hash Identifier & Analyzer
Identify and analyze hash types from hash strings. Supports MD5, SHA-1, SHA-2, SHA-3, bcrypt, Argon2, scrypt, PBKDF2, and more. Analyzes hash format, length, and characteristics to determine the most likely hashing algorithm used.
HMAC Generator / Verifier (SHA‑256 / SHA‑512)
Generate HMAC (Hash-based Message Authentication Code) using SHA-256 or SHA-512 algorithms. Verify message authenticity and integrity with shared secret keys. Essential for API authentication, webhook verification, and secure communications.
MD5 Hash Generator & Verifier
Generate MD5 hashes from text input and verify text against existing MD5 hashes. MD5 produces a 128-bit hash value but is cryptographically broken - use only for non-security applications like checksums.
PBKDF2 Hash Generator & Verifier
Generate PBKDF2 hashes from passwords with configurable salt, iterations, and algorithms. Verify passwords against existing PBKDF2 hashes. PBKDF2 is the industry standard for secure password storage and key derivation, providing protection against brute force and rainbow table attacks.
Random Number Generator
Generate random numbers with customizable ranges, quantities, and options. Perfect for games, testing, sampling, and mathematical applications.
Random Password Generator
Generate secure, customizable passwords with options for length, character sets, and complexity. Create strong passwords for accounts, applications, and security purposes.
Scrypt Hash Generator & Verifier
Generate secure scrypt hashes and verify passwords against existing hashes. Scrypt is a memory-hard password hashing function designed to resist hardware-based attacks with configurable CPU/memory cost parameters.
SHA-1 Hash Generator & Verifier
Generate SHA-1 hashes from text input and verify text against existing SHA-1 hashes. SHA-1 produces a 160-bit hash value but is deprecated due to security vulnerabilities - use SHA-256 or SHA-3 for new applications.
SHA-256 Hash Generator & Verifier
Generate SHA-256 hashes from text input and verify text against existing SHA-256 hashes. SHA-256 is a secure cryptographic hash function producing 256-bit values, widely used in blockchain, digital signatures, and file integrity verification.
SHA-512 Hash Generator & Verifier
Generate SHA-512 hashes from text input and verify text against existing SHA-512 hashes. SHA-512 is the most secure hash function in the SHA-2 family, producing 512-bit values ideal for high-security applications and long-term data integrity.
SHA‑3 / Keccak Hash Generator
Generate and verify SHA-3 and Keccak hashes with support for all variants including SHAKE128/256 extendable output functions. Features the latest NIST-approved SHA-3 standard and original Keccak algorithms used in Ethereum blockchain. Next-generation cryptographic security.
UUID Generator
Generate random UUIDs (v4) for software development use. Create unique identifiers for databases, APIs, and applications with one click.
