Hi all, We are planning to use GPG tool in our application which is JAVA Based. Could you please let me know that, how can i use GPG encryption and decryption using JAVA. below is criteria on which i have to evaluate GPG Evaluate GPG tool -- i.Invoking this tool from Java. If this is not supported some other tool ii.Storage of keys/certificated in keystore iii.Using the keys/certificates for encryption & decryption. Note: Encryption and decryption will be of a given file name at any location. Means I gon't want to pass input as string but a file name. I have already gone through GNUPG.java file which does e/d of passed string. I am looking for some API which I can directly use. iv.Encrypt and decrypt for compressed as well as other files like text, pdf, excel etc.
any help will be appritiable. regards, Danesh -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alessandro Vesely Sent: Friday, May 18, 2007 12:58 PM To: gnupg Subject: Re: Secure text editor?

Ooops, I hadn't noticed that. Yes, then VirtualAlloc and VirtualLock can be used to avoid leaving traces of sensitive data on the swap file in the way you described (i.e. lock before fill and sweep before unlock.) I still think that's not the kind of task that the function has been designed for. The authorization constrain you mentioned and other possible side effect tend to make it unpractical for naive usage. However, a background console app that allocates a few memory pages for storing sensitive data (e.g. a gpg agent?) should use it to increase data security. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.
