Generate MD5, SHA-256, bcrypt hashes, UUIDs, and secure passwords.
Hashing and cryptographic utilities are essential for security, data integrity, and unique identification. This collection includes hash generators for all common algorithms (MD5, SHA-1, SHA-256, SHA-512, bcrypt), UUID generators (v4 and v7), secure password generators, and checksum verification tools. Developers use these tools to verify file integrity, generate test passwords, create unique identifiers, hash values for comparison, and understand how different algorithms work. The privacy advantage matters here more than anywhere — when you're hashing passwords or generating security tokens, you want a tool that processes everything locally.
