Description
I am signing a PKCS#7 signature using the RSA algorithm. The `authenticatedAttribute` within the `SignerInfo` structure is an ASN.1 structure, so it is signed as binary data.
To verify this signature, I need to provide the message as binary input. However, I'm unsure about the correct way to input the binary data for verification.
Is there a specific method or format for providing binary input when verifying a PKCS#7 signature with an ASN.1 structured `authenticatedAttribute`?

Research direction
The issue names no files, tests, or entry points; first locate CyberChef's PKCS#7 signature verification operation and its handling of authenticatedAttribute input. Determine the supported binary input format and document or implement a way to provide it, with verification of an ASN.1 structured authenticatedAttribute as the completion criterion.
