title: Suspend "Weak encryption keys" warning from libgcrypt->libgpg-error
body: <p>I'm using weak keys while doing cryptography with libgcrypt and I'm getting proper warnings about it from libgpg-error as "Weak encryption keys" to stderr. Problem is that I'm reading std:err into GUI, where I don't want to see them (just because getting too many of them). I can filter stderr input in GUI, but my preferable way would be to suppress the warning in more intelligent way. Unfortunately I don't have any clue how to achieve this. While reading though libgcrypt documentation I found that it allows suspending of secure memory warning only. Reading through libgpg-error source code I haven't found anything useful. </p>
  
  <p>Your advice would be much appreciated.</p>
  
  <p>Thanks in advance.
