Why each option
MD5 is a cryptographic hash function that produces a fixed-size output, making it a one-way hash algorithm used for data integrity checks.
MD5 (Message-Digest Algorithm 5) is a widely known cryptographic hash function designed to take an input of arbitrary length and produce a fixed-size, 128-bit hash value, which is computationally difficult to reverse-engineer to find the original input.
3DES (Triple Data Encryption Standard) is a symmetric-key block cipher, not a hash algorithm.
While MD5 produces a 128-bit hash, "192 bit" refers to a specific key size often associated with symmetric encryption, not a type of algorithm itself.
PKI (Public Key Infrastructure) is a system for creating, managing, distributing, and revoking digital certificates, not a specific hashing algorithm.
