 I wish application developers would understand
 a simple fact: language choice can't be computer-wide,
 it must be *application specific*.

Language choice is user specific, however users may start applications
with other language setting (cf. envvar LANG).  All modern systems (~15
years and more) use sensible defaults and allow switching to other
languages.  In fact at least on GNU systems you may do this even on a
per thread base.

Hello
I'm working on asymmetric keys for encryption and decryption of files. I am 
going to encrypt data on sender PC using receiver's public key and send 
encrypted data to receiver in order to decrypt it using its private key.
 I have two PCs (A and B). I created a (public key, private key) on A and sent 
its public key to B. the public key is attached. Then I tried to encrypt a dir 
using gpgdir command. But I encountered below error. I'm wondered why gpg is 
looking for A's private key? Whenever we don’t want B knows the private key? 
How can I fix it?

Using output from gpg --list-packets on a key to get the mpi values to generate s-expressions

2011-05-31 Thread Foo Lum
Hey guys,

I am trying to use gpg generated public keys to do encryption using
libgcrypt. I used the list packets command on the key to get me the contents
of the key and parsed the mpi values into an s-expression. So when I try to
encode my session key with my public key I get the error Odd hexadecimal
numbers in S-expression? I think list packets is maybe giving me hex
numbers without the leading zero? If so what do I need to do to get me mpi
values that I can use in libgcrypt?

Thanks in advance,

Foo
