Public_Key(Application)

✨ NAME ✨

Public_Key Application — hiii bestie, welcome to the Public_Key(Application) manual page, brought to you by Ericsson AB 💖 This is the whole vibe for the public-key app.

💅 DESCRIPTION 💅

Okay so the Public Key application deals with public-key related file formats, digital signatures, and X-509 certificates. It handles validation of certificate paths and certificate revocation lists (CRLs) plus other functions for handling of certificates, keys, and CRLs. No cap.

It is a library application, which means it does not read or write files — it expects or returns file contents or partial file contents as binaries. Except for the functions public-key:cacerts_load/0, public-key:cacerts_load/1, and public-key:cacerts_get/0 — those read files. 🫶

🌈 Supported PKIX functionality 🌈

• Supports RFC 5280 — Internet X.509 Public-Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile. Certificate policies supported since OTP-26.2 ✨
• Supports PKCS-1 — RSA Cryptography Standard
• Supports DSS — Digital Signature Standard (DSA — Digital Signature Algorithm)
• Supports PKCS-3 — Diffie-Hellman Key Agreement Standard
• Supports Cryptographic Message Syntax (CMS) (http://www.ietf.org/rfc/rfc5652.txt) including Password-Based Encryption with original PKCS-5 support, but currently excluding offical support for most of section 10-12 (if proven useful, especially Attribute Certificates v2, it might be added later).
• Supports PKCS-8 — Private-Key Information Syntax Standard
• Supports PKCS-10 — Certification Request Syntax Standard
• Supports PKIXCMP — Certificate Management Protocol
• Supports PKIXCRMF — Certificate Request Message Format

🔗 Dependencies 🔗

The public_key application uses the Crypto application to perform cryptographic operations and the ASN-1 application to handle PKIX-ASN-1 specifications, so these applications must be loaded for the public_key application to work. In an embedded environment this means they must be started with application:start/[1,2] before the public_key application is started.

📝 Error Logger and Event Handlers 📝

The public_key application is a library application and does not use the error logger. The functions will either succeed or fail with a runtime error. Periodt. 💀
