HASH

Hash Module in Vint

The Hash module in Vint provides additional hashing algorithms that complement the existing crypto module. It currently supports SHA1 and SHA512 hashing functions for generating secure hash values from text input.

Importing the Hash Module

To use the Hash module, simply import it:

import hash

Functions and Examples

1. SHA1 Hash (sha1)

The sha1 function generates a SHA1 hash from the provided string data.

Syntax:

sha1(data)

Example:

import hash

print("=== SHA1 Hash Example ===")
data = "hello world"
sha1_hash = hash.sha1(data)
print("Input:", data)
print("SHA1 Hash:", sha1_hash)
// Output: SHA1 Hash: 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed

---

2. SHA512 Hash (sha512)

The sha512 function generates a SHA512 hash from the provided string data.

Syntax:

sha512(data)

Example:

import hash

print("=== SHA512 Hash Example ===")
data = "hello world"
sha512_hash = hash.sha512(data)
print("Input:", data)
print("SHA512 Hash:", sha512_hash)
// Output: SHA512 Hash: 309ecc489c12d6eb4cc40f50c902f2b4d0ed77ee511a7c7a9bcd3ca86d4cd86f989dd35bc5ff499670da34255b45b0cfd830e81f605dcf7dc5542e93ae9cd76f

Complete Usage Example

import hash

print("=== Hash Module Complete Example ===")

// Test different types of data
test_data = [
    "hello",
    "hello world",
    "VintLang Programming Language",
    "The quick brown fox jumps over the lazy dog"
]

for data in test_data {
    print("\nInput:", data)
    print("SHA1:  ", hash.sha1(data))
    print("SHA512:", hash.sha512(data))
}

// Example with password hashing
password = "mySecretPassword123"
print("\n=== Password Hashing ===")
print("Password SHA1:  ", hash.sha1(password))
print("Password SHA512:", hash.sha512(password))

---

Use Cases

• Password Storage: Hash passwords before storing them in databases
• Data Integrity: Verify file integrity by comparing hash values
• Digital Signatures: Generate unique identifiers for data
• Checksums: Create checksums for data validation
• Security: Generate secure hash values for authentication

Summary of Functions

Function	Description	Output Length
sha1	Generates SHA1 hash from string data	40 characters
sha512	Generates SHA512 hash from string data	128 characters

Both functions return hexadecimal string representations of the hash values, making them easy to store and compare.
