[pkg-cryptsetup-devel] Bug#942497: cryptsetup: Adiantum cipher cannot be specified in the /etc/crypttab

[Krisztián Kende]

Package: cryptsetup
Version: 2:2.2.1-1
Severity: normal

Dear Maintainer,

In the /etc/crypttab file the fourth, options field separates each option with a comma.
The

xchacha12,aes-adiantum-plain64
xchacha20,aes-adiantum-plain64

valid ciphers cannot be specified in the options field, because the comma is misinterpreted.

The error message is:

> cryptdisks_start <name>
cryptsetup: WARNING: <name>: ignoring unknown option 'aes-adiantum-plain64'
