如何將 RSA 私鑰轉換為 pem

Question

我需要將使用 RsaPrivateKey::new() 生成的私鑰轉換為 pem 但無法通過文檔弄清楚如何執行此操作

use rsa::{PublicKey, RsaPrivateKey, RsaPublicKey, PaddingScheme, pkcs8::EncodePrivateKey};

// create a private key
let mut rng = rand::thread_rng();
let bits = 2048;
let private_key = RsaPrivateKey::new(&mut rng, bits).expect("Failed to generate key");
// create a public key / address
let public_key = RsaPublicKey::from(&private_key);

創建 pem 會返回一個錯誤，指出 LineEnding 未聲明，但他們在文檔中就是這樣做的：

let priv_pem = RsaPrivateKey::to_pkcs8_pem(&private_key, line_ending: LineEnding::default);

Answer 1

您需要從 pkcs8 導入 LineEnding，或將其限定為來自該板條箱：

use rsa::pkcs8::{LineEnding, EncodePrivateKey};

let priv_pem = RsaPrivateKey::to_pkcs8_pem(&private_key, LineEnding::default);

或者

use rsa::pkcs8::{self, EncodePrivateKey};

let priv_pem = RsaPrivateKey::to_pkcs8_pem(&private_key, pkcs8::LineEnding::default);
