How this entity was disambiguated
This entity first appeared as the object of triple T1711854 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: PKCS #7 Context triple: [PKCS #1, relatedTo, PKCS #7]
-
A.
PKCS #1
PKCS #1 is a cryptographic standard that defines the mathematical properties, formats, and padding schemes for implementing RSA encryption and digital signatures.
-
B.
PGP
PGP (Pretty Good Privacy) is an encryption program that provides cryptographic privacy and authentication for data communication, most notably for securing emails and files.
-
C.
S/MIME
S/MIME is a widely used standard for secure email that provides encryption and digital signatures using public key cryptography.
-
D.
ASN.1
ASN.1 (Abstract Syntax Notation One) is a standardized, platform-independent notation used to define and encode complex data structures in telecommunications and cryptographic protocols, including X.509 certificates.
-
E.
Encapsulating Security Payload
Encapsulating Security Payload (ESP) is a core IPsec protocol that provides confidentiality, integrity, and optional authentication for IP packets through encryption and encapsulation.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: PKCS #7 Description of subject: PKCS #7 is a cryptographic standard that defines the syntax for digitally signing and encrypting data, forming the basis for formats like S/MIME and CMS (Cryptographic Message Syntax).
