Об TIGER128,3 хэш
The Tiger hash function family includes various versions such as Tiger128, Tiger160, and Tiger192, each producing hash values of different lengths (128, 160, and 192 bits, respectively). Tiger128,3 specifically refers to Tiger with a 128-bit hash output and a 3-pass approach.
Key Characteristics of Tiger128,3:
Output Size: 128 bits (16 bytes).
Passes: The '3' in Tiger128,3 indicates that the algorithm processes the input data three times.
Algorithm: Tiger hash function uses a stream cipher methodology based on iterating rounds of transformations on the input data. It operates in multiple passes to enhance its cryptographic strength.
Usage: Tiger128,3 can be used in applications where a 128-bit hash is sufficient for integrity checks, message authentication, or other cryptographic operations. However, it's important to note that Tiger hash functions, including Tiger128,3, are not as widely used as some other cryptographic hash functions like SHA-256 or SHA-512.
Example Implementation in Python:
To compute the Tiger128,3 hash of a string in Python, you would typically use a library or an implementation that supports Tiger hashing. Here’s a conceptual example using a hypothetical tiger library (note that such a library would need to be sourced or implemented separately):
import tiger
def tiger128_3_hash(data):
# Assuming a hypothetical 'tiger' library with Tiger128,3 implementation
hash_value = tiger.hash128_3(data.encode('utf-8'))
return hash_value
# Example usage
input_data = "Hello, World!"
hash_value = tiger128_3_hash(input_data)
print(f"Tiger128,3 hash for '{input_data}': {hash_value}")
Conclusion:
Tiger128,3 is a hash function variant that provides a 128-bit hash output and operates with three passes over the input data to enhance security. While it may not be as commonly used as some other hash functions, it remains suitable for applications requiring a moderate level of cryptographic strength and efficiency for 128-bit hash operations.
