To provide integrity of data, hashing is often used. Which of the following is a commonly used 128-bit hash digest?
|
|
SHA-1
|
|
|
MD-5
|
|
|
CRAMMD5
|
|
|
SHA-256

Explanation:
Detailed explanation-1: -MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function that results in a 128-bit hash value. The 128-bit (16-byte) MD5 hashes (also termed message digests) typically are represented as 32-digit hexadecimal numbers (for example, ec55d3e698d289f2afd663725127bace).
Detailed explanation-2: -Message Digest (MD) It is a 128-bit hash function. MD5 digests have been widely used in the software world to provide assurance about integrity of transferred file.
Detailed explanation-3: -Conclusion. To conclude, MD5 generates a message digest of 128-bits, while SHA1 generates a message digest of 160-bit hash value. Hence, SHA1 is a relatively complex algorithm and provides better security than MD5.
