Detailed explanation-1: -MD5 (Message-Digest algorithm 5) is a hashing algorithm, commonly used to verify integrity when downloading or transferring files.
Detailed explanation-2: -Explanation. Secure Hash Algorithm (SHA) is one of many available hashing algorithms used to verify data integrity.
Detailed explanation-3: -Checksums are used to check files and other data for errors or manipulation that might have occurred during data transmission or storage. Cryptographic checksums are the basis for digital signatures and other use cases of cryptography and encryption.
Detailed explanation-4: -Hash-based verification ensures that a file has not been corrupted by comparing the file’s hash value to a previously calculated value. If these values match, the file is presumed to be unmodified.
Detailed explanation-5: -Hash values are also useful for verifying the integrity of data sent through insecure channels. The hash value of received data can be compared to the hash value of data as it was sent to determine whether the data was altered.
