FW: [Cryptix-users] Problem with Cryptix JCE Provider

[Kapadi, A. <AK...@ti...>]

Hi,
=20
  I was able to solve the problem I had below. Now I am able to encrypt the=
 Text or ASCII file using Cryptix but when the file size is big (>10Mb), it=
 takes a long time to do the encryption. The following is code snippet I am=
 using.=20
=20
 java.io.BufferedReader in =3D new java.io.BufferedReader(new java.io.FileR=
eader(new java.io.File(textFile)));
            String line =3D null;
            while ((line=3Din.readLine()) !=3D null) {
                msg =3D msg.concat(line);
                msg =3D msg.concat("\n");
            }
            in.close();
            LiteralMessageBuilder lmb =3D LiteralMessageBuilder.getInstance=
("OpenPGP");
            lmb.init(msg.getBytes());
            litmsg =3D (LiteralMessage) lmb.build();=20
=20
I used to pass the string object to INIT method of LiteralMessageBuilder bu=
t changed to bytes assuming it would be faster. It is faster compared to wh=
en I used to pass the string but still it takes around 2hrs+ to encrypt any=
 file bigger than 10Mb. Did any one encounter this problem? Any suggestions=
 to improve the speed?=20

Thanks,=20

Hi,=20

  I am having problem while encrypting a text file using Cryptix. I am usin=
g RSA legacy (2048 bit) key for encryption. When I run my program to do the=
 encryption, I get an error saying=20

"Exception in thread "main" java.lang.SecurityException: invalid SHA1 signa=
ture File digest for cryptix/jce/provider/rsa/RSAPublicKeyCryptix.class"

 I have downloaded all the related jar files and also unlimited strength po=
licy file from Sun. I am not able to figure out what else could be going wr=
ong. Any help would be greatly appreciated.

Thanks,=20
