Supported Hash Algorithms

MD5 (Message-Digest Algorithm 5)

A 128-bit hash function. While no longer recommended for security purposes, it's still widely used for checksums and non-cryptographic applications.

SHA-1 (Secure Hash Algorithm 1)

A 160-bit hash function. Deprecated for security use but still found in legacy systems and version control (Git).

SHA-256

A 256-bit hash from the SHA-2 family. Widely used in security applications, including Bitcoin and SSL certificates.

SHA-512

A 512-bit hash offering higher security than SHA-256. Used when maximum security is required.

Base64

Not a hash but an encoding scheme. Converts binary data to ASCII text for safe transmission over text-based protocols.

tools.common.faq

What is a hash function?

A hash function converts input data of any size into a fixed-size output (hash). The same input always produces the same hash, but it's computationally infeasible to reverse the process.

Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. For checksums and non-security applications, MD5 is faster. Never use MD5 or SHA-1 for password hashing or security-critical applications.

Is my data sent to a server?

No, all hashing is performed locally in your browser using the Web Crypto API. Your data never leaves your device.
