| TurboSFV XE v11.10 - Algorithm name as checksum file type |
Notes to TurboSFV v11.10:
Starting with this new version, the algorithm name can be used for the filename extension of the checksum file. Up to now, there was only a default extension, consists of three characters and based on the hash family, to which the
algorithm belongs. By using the new file types, the name of the checksum file already indicates, which algorithm produced the hash
values.
This was not the case, for example, with the offered algorithms from the SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512 plus SHA-512/224 and SHA-512/256): A standard extension ".sh2" was automatically added to the file name, which
indicates only the
family.
Internally, the output length of the algorithm determines the algorithm. But this doesn't work for algorithms with the same output length, here for example SHA-256 and SHA-512/256. So in this case, additional flags in the checksum file
must point to the used algorithm, otherwise a checksum can't be validated. By using the new file types, the file extension clearly identifies the used algorithm and additional flags are no longer needed.
However, both file types, based on the hash family and on the algorithm, are available and the preferred one can be set as the default for the save dialog, while the other type can be alternatively used. The configuration provides options
to preselect the file type. Similar can be done for the command-line version, by specifying the new special switch
"/ne".
Furthermore, a loaded or validated checksum file can be exported to a new hash file, by using the export functionality. While saving, again both file types are offered. Thus, the export function can also be used to convert from one type to
the
other.
Final hint: The "Search and Validate" functionality, which searches for checksum files in a given folder tree and validates the hash values, works for the old and new file types, whether or not they are registered. A file type must be
registered to let the shell know, which program to use, if a file is opened via the
shell.
