Text Hash Generator

Hash functions are mathematical algorithms that convert data of arbitrary size to a fixed-size string of characters. They are designed to be one-way functions, making it practically impossible to reverse the process and generate the original input from the hash.

Key properties of cryptographic hash functions:

• Deterministic: The same input will always produce the same hash output
• Fast to compute: It should be quick to calculate the hash of any input
• Pre-image resistance: Given a hash value, it should be difficult to find any input that hashes to that value
• Small changes cause big differences: A small change in the input produces a completely different hash output
• Collision resistance: It should be difficult to find two different inputs that hash to the same output

Security Note: MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes. SHA-256 and above are currently considered secure for most applications.

Below are examples of how the text Hello World is hashed using different algorithms:

Hash Functions in Different Languages

Here are examples of how to generate SHA-256 hashes in different programming languages:

const crypto = require('crypto');
const hash = crypto.createHash('sha256').update('Hello World').digest('hex');
// Result: 'a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e'
                

import hashlib
hash_object = hashlib.sha256(b'Hello World')
hex_dig = hash_object.hexdigest()
# Result: 'a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e'
                

$hash = hash('sha256', 'Hello World');
// Result: 'a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e'
