Formula: crypto.subtle.digest(algorithm, data)
Hash Generator
Cryptographic hash functions produce a fixed-size output from any input, used for data integrity verification and password storage.
Conversion Formula
crypto.subtle.digest(algorithm, data)
The text is encoded to bytes, processed through the hash algorithm, and the result is displayed as hexadecimal.
Step-by-Step Examples
"hello" with SHA-256 = 2cf24dba5fb0a30e...
64-character hex string
Frequently Asked Questions
What is a hash function?
A hash function converts input data into a fixed-length string of characters. The same input always produces the same hash.
Is SHA-256 better than MD5?
Yes, SHA-256 is more secure. MD5 is considered broken for cryptographic purposes due to collision vulnerabilities.
Can hashes be reversed?
Hash functions are one-way — you cannot derive the original input from the hash. However, common inputs can be found via rainbow tables.
