Об TIGER160,3 хэш
Tiger160,3 is a variant of the Tiger hash function that produces a fixed-size hash of 160 bits (20 bytes). The "3" in Tiger160,3 denotes the number of passes (iterations) the algorithm performs on the input data during hashing.
Key Characteristics of Tiger160,3:
Output Size: 160 bits (20 bytes).
Passes: Tiger160,3 performs 3 passes (iterations) on the input data. Each pass involves a series of mixing and transformation operations.
Algorithm: Tiger hash functions use a stream cipher approach with multiple rounds of mixing to process the input data. This iterative process aims to enhance the cryptographic strength of the hash function.
Usage: Tiger160,3 can be used in applications where a 160-bit hash is required, such as digital signatures, data integrity checks, and other cryptographic operations.
Example Implementation in Python:
To compute the Tiger160,3 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_3_hash(data):
# Assuming a hypothetical 'tiger' library with Tiger160,3 implementation
hash_value = tiger.hash160_3(data.encode('utf-8'))
return hash_value
# Example usage
input_data = "Hello, World!"
hash_value = tiger160_3_hash(input_data)
print(f"Tiger160,3 hash for '{input_data}': {hash_value}")
Conclusion:
Tiger160,3 provides a 160-bit hash output and utilizes an iterative approach to hashing, which helps in enhancing its security. It's suitable for applications that require a fixed-size hash of this length and can be used alongside other cryptographic functions for data integrity verification and message authentication.
