Crate tsumiki_pem 

tsumiki-pem

PEM (Privacy Enhanced Mail) format handling for cryptographic data.

This crate implements RFC 7468 for encoding and decoding PEM format.

What is PEM?

PEM is a text-based format for encoding binary data. It wraps base64-encoded data with boundary markers like:

-----BEGIN CERTIFICATE-----
MIIBkTCB+wIJAKHHCgVZU...
-----END CERTIFICATE-----

Supported Labels

• CERTIFICATE - X.509 certificates
• PRIVATE KEY - PKCS#8 private keys
• ENCRYPTED PRIVATE KEY - PKCS#8 encrypted private keys
• RSA PRIVATE KEY - PKCS#1 RSA private keys
• EC PRIVATE KEY - SEC1 EC private keys
• PUBLIC KEY - X.509 SubjectPublicKeyInfo
• RSA PUBLIC KEY - PKCS#1 RSA public keys

Example

use std::str::FromStr;
use tsumiki_pem::{Pem, Label};

let pem_text = "-----BEGIN CERTIFICATE-----\nAAA=\n-----END CERTIFICATE-----";
let pem = Pem::from_str(pem_text)?;

assert_eq!(pem.label(), Label::Certificate);

Decoding to Raw Bytes

use std::str::FromStr;
use tsumiki::decoder::Decoder;
use tsumiki_pem::Pem;

let pem_text = "-----BEGIN CERTIFICATE-----\nAAA=\n-----END CERTIFICATE-----";
let pem = Pem::from_str(pem_text)?;

// Decode to raw bytes
let bytes: Vec<u8> = pem.decode()?;

Modules
