  <summary>Recommended update for cryptsetup</summary>
  <description>This update for cryptsetup fixes the following issues:

Update from version 2.0.5 to version 2.0.6. (jsc#SLE-5911, bsc#1165580)

- Fix support of larger metadata areas in *LUKS2* header.

This release properly supports all specified metadata areas, as documented
  in *LUKS2* format description.
  Currently, only default metadata area size is used (in format or convert).
  Later cryptsetup versions will allow increasing this metadata area size.

- If *AEAD* (authenticated encryption) is used, cryptsetup now tries to check
  if the requested *AEAD* algorithm with specified key size is available in kernel crypto API.
  This change avoids formatting a device that cannot be later activated.

For this function, the kernel must be compiled with the *CONFIG_CRYPTO_USER_API_AEAD* option enabled. 
  Note that kernel user crypto API options (*CONFIG_CRYPTO_USER_API* and *CONFIG_CRYPTO_USER_API_SKCIPHER*) 
  are already mandatory for LUKS2.

- Fix setting of integrity no-journal flag. Now you can store this flag to metadata using *\--persistent* option.

- Fix cryptsetup-reencrypt to not keep temporary reencryption headers if interrupted during initial password prompt.

- Adds early check to plain and LUKS2 formats to disallow device format if device size is not aligned to requested 
  sector size. Previously it was possible, and the device was rejected to activate by kernel later.

- Fix checking of hash algorithms availability for *PBKDF* early. Previously *LUKS2* format allowed non-existent hash 
  algorithm with invalid keyslot preventing the device from activation.

- Allow Adiantum cipher construction (a non-authenticated length-preserving fast encryption scheme), so it can be used
  both for data encryption and keyslot encryption in *LUKS1/2* devices.

For benchmark, use:
    
      # cryptsetup benchmark -c xchacha12,aes-adiantum
      # cryptsetup benchmark -c xchacha20,aes-adiantum

For LUKS format:
  
      # cryptsetup luksFormat -c xchacha20,aes-adiantum-plain64 -s 256 &lt;device&gt;
