Openssl Man pages

I have found a few of the openssl commands but there are loads missing and I can't find them anywhere.

Eg
-inkey
-in
-A
what do all these do??????

Does anyone know where there is a definitive list of Openssl commands??

If so please let me know..
Thanks.

I think these are called options, not commands?

If I remember correctly, I think -inkey is to specify an input file containing the key. For RSA signing, for example, it is the signer's private key. -in is the input file, possibly a PEM-encoded certificate.

I didn't recall ever seeing -A. Yeah, it doesn't document everything and when I had to use OpenSSL in my final project I did have to read portions of the source code though. I know there's a book for openssl (o'reilly??) but I don't know how complete it is because I have not read it before.
