| TurboSFV v10.11 - Identify hash algorithm in checksum file |
Notes to TurboSFV v10.11:
In TurboSFV, the available hash algorithms are grouped by their families, for example the hash functions SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256 belong to the SHA-2 family. For each family, TurboSFV registers one
file extension in the operating system, so that TurboSFV already knows the hash family by interpreting the name of the extension. In order to identify the algorithm, TurboSFV looks for the length of the checksum, which is for example 384 Bits
in case of SHA-384. This however doesn't always work, because for example SHA-256 and SHA-512/256 come with the same output
length.
Thus, in this case, a unique identifier is needed to be able to distinguish between the two algorithms. Up to now, the identifier is written to the checksum file along with the checksum. This can however create a problem, if you want to
open the checksum file with another application, which only expects the checksum and not an
identifier.
In this new version, you now have the option to specify, where the unique identifier appears in the checksum file: Either together with each checksum or once for all checksum as a commentary line. This is a configuration value, which can
be specified in the configuration on page "Hash file". For the command-line version, there is a new switch "/q", which provides the same
functionality.
Important to know is, that previous versions of TurboSFV are not aware of this new option and can fail to identify the algorithm, if used.
Feel free to add a comment regarding this new version here.
