/SubFilter array
(Optional) An array of names indicating encodings to use when signing. The first name in the array that matches an encoding supported by the signature handler shall be the encoding that is actually used for signing. If SubFilter is specified and the Ff entry indicates that this entry is a required constraint, then the first matching encodings shall be used when signing; otherwise, signing shall not take place. If Ff indicates that this is an optional constraint, then the first matching encoding shall be used if it is available. If none is available, a different encoding may be used.
Qualificateur : Optional
