The MD5 (Message-Digest Algorithm 5) program is primarily used to compute a hash value or checksum for a file. The MD5 hash function produces a 128-bit hash value, typically represented as a 32-character hexadecimal number. This hash value is unique to the contents of the file, making it useful for verifying data integrity and detecting any changes or corruption.
Key uses of the MD5 program include:
File Integrity Verification: Ensuring that files have not been altered or corrupted during transmission or storage.
Digital Signatures: Verifying the authenticity and integrity of digital documents and software.
Password Hashing: Storing hashed passwords securely in databases.
Data Deduplication: Identifying duplicate files by comparing their hash values.
