# Kwallet Setup to Secure Directory
|
|
#
|
|
# Kwallet will be used for storing passwords for most KDE- Applications, like for Nextcloud- Client, Talk app and many more.
|
|
# Usually Kwallet will ask for a password to have good security in your encrypted file, but this will make Logon non Interactive and is annoying for the user.
|
|
# Or, even worse, the first time you logon, the wallet will be created with your current password. But when it changes on the Domain, after new logon you will be asked
|
|
# and you must enter the OLD password, breaking all apps, that are needing password if the old password was lost. This is a very bad situation.
|
|
# Instead we will check to have the Passwords opened without a seperate password set, but to have them encrypted at a secure place by the domain-encryption.
|
|
#
|
|
# Basically, this script checks, if the Walletfile can be used without password and if it is located in the encrypted directory for security.
|
|
# Otherwise it will setup a the Walletfile into the encrypted Data-Directory and make it useable.
|
|
#
