Password & Security
13 tools in this category
Tools for generating and inspecting passwords, hashes, tokens, and unique identifiers. The security-adjacent utilities developers and everyday users reach for while building or securing an account.
Generate a strong password, then check it with the Strong Password Checker before using it.
Create SHA-256, SHA-512, or MD5 hashes, or a batch of UUIDs or ULIDs for test data and database keys.
Decode a JWT to inspect its header and payload without pasting it into a third-party site.

Password Generator
Generate strong, random passwords with custom length and character rules, helping you avoid weak or reused passwords across your accounts.
Strong Password Checker
Evaluate a password's strength against common criteria like length and character variety, and find specific weaknesses before you use it.
Hash Generator
Generate SHA-1, SHA-256, SHA-512, and other hash values from any text input, useful for checksums, data integrity checks, and basic crypto tasks.
MD5 Generator
Generate the MD5 hash of any text input, commonly used for basic checksums and legacy compatibility rather than security-sensitive purposes.
SHA1
Compute the SHA-1 hash of any text input, historically used for checksums and digital signatures though now considered weak for security.
SHA256
Compute the SHA-256 hash of any text input, widely used for checksums, digital signatures, and general cryptographic purposes today.
SHA512
Compute the SHA-512 hash of any text input, offering a longer, more collision-resistant hash than SHA-256 for extra security margin.
HMAC Generator
Generate a keyed HMAC hash using a secret key combined with your message, used to verify both integrity and authenticity, common in API auth.
UUID Generator
Generate random version 4 UUIDs in bulk, universally unique identifiers commonly used as database keys, session tokens, or object references.
JWT Decoder
Decode a JSON Web Token into its header and payload sections so you can inspect the claims inside without needing the signing secret.
JWT Generator
Create a signed JSON Web Token from a custom payload and secret key, useful for testing authentication flows during development.
QR Code Generator
Turn any text, URL, or piece of data into a scannable QR code that you can download and use in print, packaging, or a digital design.
ULID / Nanoid Generator
Generate sortable ULIDs or compact, URL-safe Nanoids in bulk, a modern alternative to UUIDs for database keys and identifiers.
