기능

Several enhancements for digital signatures and certificate security including the following:

  • Supports EMSA-PSS encoding scheme for RSA signatures. (EMSA-PSS = Encoding Method for Signatures Appendix, Probabilistic Signature Scheme).
  • Supports OAEP for RSA certificate security. (OAEP = Optimal Asymmetric Encryption Padding).
  • Reject input documents with certification signatures and permissions=nochanges unless the "sacrifice" option has been supplied to avoid breaking existing certification signature.
  • No longer requires "conformance=extended" for NIST-15 elliptic curves other than P-256/P-384/P-521 since these are supposed to be supported in Acrobat.
  • Increased the default value of "timestampsize" to accommodate changes implemented in the configuration of a commonly used TSA.
