如何将RSA私钥转换为pem

Question

我需要将使用RsaPrivateKey::new()生成的私钥转换为pem，但无法通过文档找出如何做到这一点

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);

创建pem返回一个错误，说LineEnding未声明，但这就是他们在文档中的做法:

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

Answer 1

您需要从pkcs8导入LineEnding，或者将其限定为来自该crate:

use rsa::pkcs8::{LineEnding, EncodePrivateKey};
let priv_pem = RsaPrivateKey::to_pkcs8_pem(&private_key, LineEnding::default);

或

use rsa::pkcs8::{self, EncodePrivateKey};
let priv_pem = RsaPrivateKey::to_pkcs8_pem(&private_key, pkcs8::LineEnding::default);
