Feature request: PKCS#7 Signature Verification with Binary authenticatedAttribute: Input Format

[siprikorea]

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?
