How to Use the Hash Generator

Enter or paste any text into the input field above, select which hash algorithms you want to generate, and click "Generate Hashes." The tool will instantly compute the hash values using your browser's built-in Web Crypto API.

What is Hashing?

Hashing is the process of converting input data of any size into a fixed-size string of characters using a mathematical algorithm. Hash functions are one-way operations — you cannot reverse a hash back to its original input. They are widely used in data integrity verification, digital signatures, password storage, and blockchain technology.

Common Hash Algorithms

• MD5 — Produces a 128-bit hash (32 hex chars). Fast but cryptographically broken. Used for checksums and non-security purposes.
• SHA-1 — Produces a 160-bit hash (40 hex chars). Deprecated for security use but still common in legacy systems.
• SHA-256 — Produces a 256-bit hash (64 hex chars). Widely used and considered secure. Standard for TLS certificates and Bitcoin.
• SHA-384 — Produces a 384-bit hash (96 hex chars). Part of the SHA-2 family, used in high-security applications.
• SHA-512 — Produces a 512-bit hash (128 hex chars). The strongest in the SHA-2 family, ideal for maximum security requirements.

Hash vs. Encryption

Hashing is a one-way process — you cannot reverse it to recover the original data. Encryption is a two-way process — encrypted data can be decrypted back to its original form with the correct key. Use hashing for data integrity and password verification; use encryption when you need to recover the original data.
