Upon downloading a new ISO, an administrator is presented with the following string: 59d15a16ce90cBcc97fa7c211b767aB Which of the following BEST describes the purpose of this string?

XSS (Cross-Site Scripting) verification relates to web application security and preventing script injection, not file integrity.

AES-256 is an encryption algorithm, not a verification method represented by a public string for file integrity.

The string shown (e.g., a SHA-256 or MD5 hash) is a cryptographic hash, which is a fixed-size alphanumeric value computed from the contents of a file. Administrators use this hash to compare it with a hash provided by the software vendor to confirm the downloaded ISO file's integrity and authenticity, ensuring it hasn't been altered or corrupted.

Digital signature verification uses cryptographic keys to verify the sender's identity and file integrity, but the string itself is a hash, which is part of a digital signature process, not the signature itself, and hash verification is a more direct description of its standalone purpose.
