How can I compile openssl with IDEA?
In INSTALL file is only descripted how can I compile without any cipher

You don't need the -idea option to decrypt a key. It automatically works
out the encryption algorithm used so that:

openssl rsa -in key.pem -out unencryptedkey.pem

would work. The -idea option is only used to use IDEA when encrypting
the key.

However if your version of 'openssl rsa' doesn't recognise the -idea
option its possible that OpenSSL was compiled without IDEA support. You
may have to recompile it. See what 'openssl version -a' outputs.
