Checksum Checksum is a fixed-size numerical representation of a piece of data of arbitrary length.
Checksum file Checksum file is a file that contains a list of file paths and their respective checksum or hash values. Usually used to verify file integrity.
CRC-32 CRC-32 (Cyclic Redundancy Check) is a hash function with a 32-bit hash value.
Cryptographic hash algorithm Cryptographic hash algorithms map binary values of an arbitrary length to small binary values of a fixed length, known as hash values, message digests or simply digests.
Digest Also known as hash value and message digest, it is a unique and extremely compact numerical representation of a piece of data. It is computationally improbable to find two distinct inputs that hash to the same value.

MD5 MD5 (Message-Digest algorithm 5) is a cryptographic hash function with a 128-bit hash value.
Process Process is an instance of a program being executed.
Regular expression Regular expression is a text string that defines a search pattern.
RIPEMD-160 RIPEMD-160 (RACE Integrity Primitives Evaluation Message Digest) is a cryptographic hash function with a 160-bit hash value.
SHA-1 SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function with a 160-bit hash value designed by the National Security Agency (NSA).
SHA-2 SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384 and SHA-512) designed by the National Security Agency (NSA).
