Python SHA256
In Python, you can use the hashlib library to calculate the SHA-256 hash of a string or bytes data. SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value, commonly represented as a hexadecimal string.
Here’s how you can calculate the SHA-256 hash in Python:
import hashlib
def calculate_sha256(data):
# Convert data to bytes if it’s not already
if isinstance(data, str):
data = data.encode()
# Calculate SHA-256 hash
sha256_hash = hashlib.sha256(data).hexdigest()
return sha256_hash
# Example usage:
input_data = "Hello, World!"
hash_value = calculate_sha256(input_data)
print("SHA-256 Hash:", hash_value)
Replace the input_data variable with the string or data you want to calculate the SHA-256 hash for. The calculate_sha256 function will return the hexadecimal representation of the SHA-256 hash.
