Interpreting the Identifier

  • The 32-character string b78b8e959e464f7a9d1df64477bb7326 matches the length and character set of an MD5 hash (32 hex chars). It could be:
    • MD5 checksum of the file contents or filename.
    • A truncated SHA-1 or other hash (less likely).
    • A repository-generated unique ID.
  • Recommendation: treat it as a checksum candidate; verify using common hash tools.
