I got this description for SKey block in documentation for generating XML request
Element: Skey (mandatory): Value of this element is base-64 encoded value of encrypted 256-bit AES session key. Session key must be dynamically generated for every transaction (session key must not be reused) and must not be stored anywhere except in memory. See next chapter for encryption details.
Attributes: ci – (mandatory) Public key certificate identifier using which “skey” was encrypted. UIDAI may have multiple public keys in field at the same time. Value of this attribute is the certificate expiration date in the format “YYYYMMDD”. Expiry date of the certificate can be obtained from the certificate itself
And I want something like this:-
