Hi...

I'm trying to implement rsa algorithm into my program by using libgcrypt
functions.I had a look at some examples under the test directory but i still
have some doubts about encrypting and decrypting.Where i can find some
more example on how to encrypt and decrypt strings with gcry_pk(encrypt|
decrypt)?? I have also some doubts on how to save key on files;what format
should i use?!

Thanks in advance

Well, it's your decision. Libgcrypt does not implement formats like
OpenPGP or SSH key blobs (although you could implement them on top of
Libgcrypt). Storing the key material (i.e. the MPI values) is easy to
do; another approach, which is used by gpg-agent, is to store complete
S-Expressions.

I stored them as S-exp in CANON format and it seems they work absolutely fine

Thanks
