Understanding Hash Algorithms
A hash function takes an input and produces a fixed-length string of characters. The same input always produces the same output, but even a tiny change in input produces a completely different hash. This makes hashes ideal for verifying data integrity and storing passwords securely.
Which Algorithm to Use?
MD5 and SHA-1 are legacy algorithms useful for checksums but not recommended for security. SHA-256 is the current standard for security applications. SHA-512 offers even more bits but is rarely needed. For generating secure tokens, use the Password Generator or UUID Generator. Encode hash outputs with the Base64 Encoder. Test hashing in the Online Code Editor.
Frequently Asked Questions
What hash algorithms are supported?
MD5, SHA-1, SHA-256, SHA-384, and SHA-512.
Is MD5 secure?
MD5 is no longer considered secure for cryptographic purposes but is still useful for checksums and file integrity verification.
Can I hash files?
Yes, switch to File Input tab and upload any file to generate its hash.
Are my files uploaded?
No. All hashing runs in your browser using the Web Crypto API. Nothing is sent to any server.
Can I reverse a hash?
No. Hash functions are one-way. You cannot recover the original input from a hash output.
Is it free?
Yes, 100% free with no limits.
