From the cipher suites tls_rsa_with_aes_128_cbc_sha256
and tls_ecdhe_ecdsa_with_aes_128_cbc_sha256
how do I know what will be the RSA , ECDHE, and ECDSA key support in IBM cloud Watson?

1The key size for (symmetric) data encryption is negotiated as part of the ciphersuite, See [https://stackoverflow.com/a/41685647/1820553] – kelalaka Oct 22 '20 at 10:46

1And the Watson has pages for that too. I've googled just IBM Watson RSA key size. https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.icha700/keysizec.htm – kelalaka Oct 22 '20 at 10:51

1In other words: the size of the RSA and ECDSA keys depend on the certificates of the parties. I have no idea for the ECDHE parameters, especially when the parties have ECDSA keys with differing parameters/curves. – fgrieu Oct 22 '20 at 11:06

i think the Watson pages that you've mentioned is actually for mainframes not for ibm watson cloud...https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.icha700/keysizec.htm – wanglen soram Oct 24 '20 at 08:41
