VerifyDigitalSig

The VerifyDigitalSig component, which usually appears in the Verify Digital Signature stage of a Commerce Interchange Receive pipeline, verifies the digital signature on the data stored in the working_data field on the Transport Dictionary.

• Verify Signature and Message XML Format. Specifies that both the digital signature and the original message have been formatted using XML.
• Verify Signature and Message PKCS7 Standard. Specifies that both the digital signature and the original message have been formatted using the Public Key Crypto System (PKCS).
• Verify Signature Only PKCS7 Standard. Specifies that only the digital signature (and not the original message) has been formatted using the Public Key Crypto System (PKCS).
• Message Field. Specifies the field in the Transport Dictionary from which the VerifyDigitalSig component reads the message data.
• Signature. (Used only if you have selected Verify Signature Only PKCS7 Standard.) Specifies the field in the Transport Dictionary from which the VerifyDigitalSig component reads the digital signature.
• Verified Message Field. Specifies the field in the Transport Dictionary to which the VerifyDigitalSig component writes the verified message.
  • Text Output. Specifies that the message is to be written into the field on the Transport Dictionary in text format.
  • Binary Output. Specifies that the message is to be written into the field on the Transport Dictionary in binary format.
• Write Certificate used to verify signature to field. Specifies the name of the field on the Transport Dictionary to which the component writes the name of the certificate used to verify the digital signature. If the verification fails, the field contains NULL.

Remarks

If the digital signature is verified, the stream of bytes stored in working_data, minus the digital signature, is re-written to the working_data name/value pair, overwriting the original data stored in that name/value pair.
