Об TIGER160,4 хэш
Tiger160,4 is a variant of the Tiger hash function family that produces a fixed-size hash of 160 bits (20 bytes). The "4" in Tiger160,4 indicates the number of passes (iterations) the algorithm performs on the input data during hashing.
Key Characteristics of Tiger160,4:
Output Size: 160 bits (20 bytes).
Passes: Tiger160,4 performs 4 passes (iterations) on the input data. Each pass involves a series of mixing and transformation operations.
Algorithm: Tiger hash functions utilize a stream cipher methodology with multiple rounds of mixing to process the input data. This iterative process aims to enhance the cryptographic strength of the hash function.
Usage: Tiger160,4 can be used in applications where a 160-bit hash is required for tasks such as digital signatures, data integrity verification, and other cryptographic operations.
Example Implementation in Python:
To compute the Tiger160,4 hash of a string in Python, you would typically use a library or an implementation that supports Tiger hashing. Here's an example using a hypothetical tiger library (note that such a library would need to be sourced or implemented separately):
import tiger
def tiger160_4_hash(data):
# Assuming a hypothetical 'tiger' library with Tiger160,4 implementation
hash_value = tiger.hash160_4(data.encode('utf-8'))
return hash_value
# Example usage
input_data = "Hello, World!"
hash_value = tiger160_4_hash(input_data)
print(f"Tiger160,4 hash for '{input_data}': {hash_value}")
Conclusion:
Tiger160,4 provides a fixed-size hash of 160 bits and utilizes an iterative approach to hashing, which contributes to its cryptographic strength. It is suitable for applications requiring this specific hash length and can be used alongside other cryptographic functions for various security-sensitive tasks.
