because it is more secure than any other algorithm.
NTLM (NT LAN Manager) uses the MD4 hash algorithm for hashing passwords. When a user sets a password, NTLM computes an MD4 hash of the UTF-16LE encoded password. This hash is then stored in the Security Account Manager (SAM) database. However, due to its vulnerabilities, NTLM is considered weak and has largely been replaced by more secure authentication protocols like Kerberos.

The output from a hash function is referred to as the hash value, hash code, hash sum, checksum or just plain "hash" as in "the hash of the file is...". Generally a hash function is presumed to be secure or it wouldn't be used. If a hash is not secure it could be referred to as "worthless" or "false sense of security".
The number of bits used in hash values varies by algorithm. For example, the MD5 algorithm produces a 128-bit hash, SHA-1 generates a 160-bit hash, and SHA-256 outputs a 256-bit hash. Each algorithm is designed to provide a different level of security and collision resistance, with longer hashes generally offering greater security.

To securely hash data for encryption, you can use algorithms like SHA-256 or bcrypt. These algorithms take the input data and produce a fixed-length hash value. This hash value can be used as a key for encryption. It is important to use a strong and secure hashing algorithm to protect the data from being easily decrypted.
Common implementations of the Challenge Handshake Authentication Protocol (CHAP) typically use the MD5 hash algorithm. CHAP uses a challenge-response mechanism where a server sends a challenge to the client, which then computes a hash of the challenge and its password to respond. Although MD5 is widely used, it is considered less secure by modern standards, and more secure alternatives are recommended for sensitive applications.

MD5 and SHA
Both SHA-1 and SHA-0 use a 160-bit hash value. Note that "SHA-0" is a retronym for the original SHA hash algorithm. SHA-1 corrected some significant flaws in the original algorithm that yielded some serious security weakness. The TIGER hash algorithm is designed to use a 192-bit hash, but also has the capability to use 160-bit and 128-bit hash values. The HAVAL algorithm can produce hashes in lengths of 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits. One version of the RIPEMD algorithm, RIPEMD-160, has a 160-bit hash. Other versions of RIPEMD, RIPEMD-128, RIPEMD-256, and RIPEMD-320, use 128, 256, and 320-bit hashes respectively. Of these, the most common is probably SHA-1, which is available on most Windows based machines.
