About RIPEMD160 hash
RIPEMD-160 Hash Description
RIPEMD-160 is a cryptographic hash function that produces a 160-bit (20-byte) hash value, typically represented as a 40-character hexadecimal number.
How RIPEMD-160 Works:
- Padding: The input message is padded so that its length is a multiple of 512 bits, leaving space for the message length.
- Initialization: RIPEMD-160 initializes five variables to specific constants. These variables serve as the initial hash values for the algorithm.
- Processing Message in Blocks: The padded message is processed in 512-bit blocks. Each block undergoes several rounds of hashing using logical and bitwise operations.
- Final Hash Value: After processing all blocks, the resulting 160-bit hash value is the RIPEMD-160 hash of the input message.
RIPEMD-160 is designed to provide cryptographic security and is used in various applications where a longer hash length than RIPEMD-128 is required for data integrity and message authentication.
