Question about bouncy castle encryption standard

[Fino Indrasaputra]

Hello,

I need to ask a question regarding bouncy castle API encryption standard. Is
the encryption algorithms contained in bouncy castle API are international
standards or follow some standard? Can I, for example, encrypt some text
using the Java bouncy castle API and then decrypt it using another non-Java
program?

I ask this because I once tried to make a 3DES encryption using the API and
decrypt it using a program made using Delphi and it just wouldn't work. The
encryptions seemed to be different between both of the programs.
Can anyone give explanation?

Thanks in advance

Yes and yes. For example, I am using the OpenPGP classes and am able to
encrypt with BouncyCastle and decrypt with a program that I have which
is written in C. (It also works the other way as well.)

Triple-DES (3DES) is difficult because there are several different
versions of it: two-key and three-key are just two variants and there
are also variations in the construction of the SP boxes. Perhaps you
could try another algorithm that does not have such variations (e.g.
CAST5).
