Hash Generator
How Hash Generation Works
Hash functions process input data to produce a fixed-length digest.
- 1
Input text is converted to bytes
The input string is encoded as UTF-8 bytes.
- 2
Hash algorithm processes the bytes
The selected algorithm (MD5, SHA-1, SHA-256, SHA-512) processes the bytes to produce a digest.
- 3
Digest is displayed as hex
The resulting hash bytes are displayed as a hexadecimal string.
FAQ
What is a hash function?
A hash function takes input data and produces a fixed-size string of characters. It is a one-way function β you cannot reverse a hash back to its original input.
Is MD5 secure?
No, MD5 is considered cryptographically broken. Use SHA-256 or SHA-512 for security purposes. MD5 is still useful for non-security checksums.
What is the difference between SHA-256 and SHA-512?
SHA-256 produces a 256-bit (32-byte) hash, while SHA-512 produces a 512-bit (64-byte) hash. SHA-512 is more secure but SHA-256 is faster on 32-bit systems.
