Smile has released new versions of PDFpen and PDFpenPro, their PDF manipulation software. Version 5.3 adds several security enhancements, including the capability to encrypt data using 128- and 256-bit Advanced Encryption Standard (AES) algorithms, which are preferred by the U.S. government and required for the storage of medical records. Also, AES-256 encryption in PDFpen now supports Unicode in passwords, and the encryption method can now be set via AppleScript. ($59.95/$99.95 new, free update, 41.4 MB)
