There is no /general/ problem using encryption in a commercial environment.

Some (reasonably popular) encryption algorithms are patented though, and for
them there are license issues. In particular, the RSA public key encryption
algorithm is patented in the US, and the IDEA symmetric key encryption is
patented in large parts of Europe. There are unencumered alternative
algorithms for both forms of encryption (e.g. Diffie/Hellman for public and
Blowfish for symmetric key encryption).

The only free SSH is OpenSSH. SSH1, like SSH2, dosn't allow commercial use,
but for SSH2 the term "commercial use" is defined (and its definition is
more strict than a common sense one).

They most likely are if they either do not use RSA, or you are not in the
