Re: Converting public key from DER to Interanl and back again

[Frank]

I have a DSA key. No I havn't. Thought the same ones worked forboth, but I guess not.

I believe you use : i2d_PulicKey() & d2i_PublicKey(). I seem to be able to convert to DER (at least the func doe snot fail). But converting it back it does not seem to, or at least totally. I run the EVP_PKEY_missing_parameters() and it fails. Also when I save the pulickey with PEM_write_PUBKEY() is it much smaller then the original. Presumably this isn't an RSA key? Have you tried i2d_PUBKEY() and d2i_PUBKEY() Steve. -- Dr Stephen N. Henson.
