Thanks for answer, Chris.
I understand that slow RSA algorithm is not used to encrypt large amounts of
data, instead of it symmetric algorithms are used.
But is it the limit of RSA-algorithm or only OpenSSL library's limit?

RSA and prepend that

I have build a fips-openssl based on the fips1.2 and openssl-0.9.8m,

it will produce the errors like this:

want to
encrypt larger things, you should split the file befor encyprting. I don´t
think openssl can do that for you 9not sure, but I don´t think it will).
Anyway, you should not use RSA for large files. RSA is too slow for that.

In the man page for rsautl, OpenSSL 0.9.7l in Mac OS X, I read this
"Note" at the bottom:
"rsautl because it uses the RSA algorithm directly can only be used to
sign or verify small pieces of data."
That seems to imply that there is a better alternative to rsautl for
