Code identifying the stated business purpose for exchanging public key on certificate information with a trading partner

Unique designation (identity) of the cryptographic process that performs authentication or encryption on data to be interchanged, or originates a cryptographic service message Note: X9 has a minimum length of 4 characters for the security originator; no mechanism, or registration method is provided by X9 or X12 to guarantee the uniqueness of the identifier

X9 has a required minimum length of 4 characters for CSC02 (security originator). No mechanism, or registration method, is provided by X9 or X12 to guarantee uniqueness of the identifier.

Unique designation (identity) of the cryptographic process that performs authentication or decryption on received data, or is the destination of a cryptographic service message Note: X9 has a minimum length of 4 characters for the security recipient; no mechanism, or registration method is provided by X9 or X12 to guarantee the uniqueness of the identifier

X9 has a required minimum length of 4 characters for CSC03 (security recipient). No mechanism, or registration method, is provided by X9 or X12 to guarantee uniqueness of the identifier.

Code specifying the type of filter used to convert data code values

CSC06, CSC07 and CSC08 provide additional information about the encoded security value field in CSC09 (C03302).
