Task File - Get Checksum​

The File - Get checksum generates a hash (checksum) value for a file and outputs it to standard output. While CRC (Cyclical Redundancy Checking) is the default algorithm, this Task also supports MD5 and several SHA (Secure Hash Algorithm) variants.

Get checksum > File filter > Location sub tab The standard VisualCron File filter is used to specify one or more files you want to retrieve the checksum for.

Checksum algorithm

Indicates the algorithm to use during calculation. The available options are:

  • CRC (default): Cyclical Redundancy Checking. Fastest and least secure.
  • MD5: Message Digest 5. Slower and more secure than CRC.
  • SHA1: Secure Hash Algorithm-1. Slower and more secure than MD5.
  • SHA256: Secure Hash Algorithm-256. Slower and more secure than SHA1.
  • SHA384: Secure Hash Algorithm-384. Slower and more secure than SHA256.
  • SHA512: Secure Hash Algorithm-512. Slowest and most secure.
