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.

 

Get Checksum > Output settings sub tab

 

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.
