Hello,

I have downloaded the ssh kdf vector from the demo server:

"algorithm": "kdf-components", "mode": "ssh", "revision": "1.0", "isSample": true, "testGroups": [ { "tgId": 1, "cipher": "AES-128", "hashAlg": "SHA-1", "testType": "AFT", "tests": [ { "tcId": 1, "k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h": "F26C9F7C7AC80976B1E044A452734524CA0177C9", "sessionId": "E192D647BF44BF5C0FCD1D797E577ED88506CE7A" },

The vector does not contain IV length and encryption key length parameters , instead contain "cipher" field. Do not how to process the vector . Any input will be help full.

Thanks , Nag

You are supposed to generate the key, iv and mac key from k via the KDF.

See the documentation of struct kdf_ssh_data in the parser what is the input and what is the expected output.

Ciao Stephan

Thanks , Nag
