title: How to use PBKDF2 password hashing in an embedded Linux device
body: <p>I have a need to generate password hashes in a Windows application and, at a later time, download them to a Linux device to be inserted into the shadow password file. For marketing reasons using PBKDF2 is attractive at the Windows end as it provides a level of FIPS certification, but I do not know how/if we can use a PBKDF2 hash in the Linux shadow password file.</p>
  
  <p>An odd requirement I know, but the Windows app is used to off-line configure the RBAC.</p>
  
  <p>I know next to nothing about Linux, but my understanding is that we use Busybox (which includes crypt) and PBKDF2 is not supported.</p>
  
  <p>Can PBKDF2 support be added? Pointers as to how?</p>
