PLOP/PLOP DS, the versatile tool for linearizing, optimizing, repairing, analyzing, en-/decrypting and ditigally signing PDF documents has been enhanced and improved.
PLOP/PLOP DS 5.2 now offers digital signatures with PSS encoding for RSA. For PDF certificate security PLOP/PLOP DS has been enhanced with OAEP padding for RSA.
PSS is mandated by various security guidelines; it is supported in Acrobat XI and DC since the January 2017 updates. RSA-OAEP offers cryptographic advantages. However, it is not currently supported in Acrobat, but only in third-party PDF viewers.
