Looking into the docs on the sourceforge site does not give any information about this point. Further, being someone with a crypto background, the userland suspend helper does have some issues with the password/key handling: 1) no support for keys containing a 0 byte. (cryptsetup can handle this) 2) the rsa functionality seems to use the unsound practice to encrypt the symmetric key directly without any padding (aka encoding in libgcrypt). This is, unfortunately, something really fundamenta... Just to add my 2 cents...
