Verify a signature of the document. These are the differences between calling this function and calling verifySignature() with the field name obtained from signature: - This function fails unless signature.getClearedIndex() returns -1. - PDF only: This function uses the DSS of the first document time stamp following the signature described by signature. If there is no such document time stamp, the latest DSS will be used. This behavior is required for verifying signatures with LTV (long term validity). . There is a setFlags() flag modifying the behavior of this function: f_relax_byte_range.
