defines the the crypto cypher to use to read the archive (default is crypto_none)

Note
  since release 2.5.0 you may and should provide crypto_none in any case (the default value) for libdar uses the algorithm stored in the archive. However you way override this (in case of corruption for example) by explicitely specifying a crypto algorithm in that case the value of the crypto algorithm stored in the archive is ignored and the algorithm used to decipher is the one specified here.

set the command to execute before reading each slice (empty string for no script)

several macros are available:

- %b : the archive basename
- %p : the slices path
- %e : the archive extension (usually "dar")

## ◆ set_lax()

void libdar::archive_options_read::set_lax | ( | bool | val | ) |
