TLS cipher control

I used PowerTCP as my TLS package. All clients get handshakes. But they
all get RC4_128_MD5 for the encryption and hashing algorithm. Can I
restrict the cipher suite available for PowerTCP TLS? For example, MD5
is known broken, can I specify a different one such as AES_128_SHA1?
I got the following answer from Dart.com (PowerTCP ventor):
the cipher is selected by the CryptoAPI which the Tool uses.
Its selection is negotiated by both sides during the handshake.
You may be able to prevent a cipher from being used by removing it from
the system's registry.
Unfortunately, I do not know where in the registry you would find the
Anybody knows where to update the registry or other ways to solve this.
Really appreciate your help!
