在Python中生成与RSA密钥签名的JWT令牌
我正在尝试转换此Java代码，以生成Python中的JWT令牌。
String privateKeyContent = privateKey
.replaceAll(Definitions.ApiGeneral.LINE_BREAKER, "")
.replace(Definitions.AuthProperty.PRIVATE_KEY_START, "")
.replace(Definitions.AuthProperty.PRIVATE_KEY_END, "");
PKCS8EncodedKeySpec keySpecPKCS8 = new PKCS8EncodedKeySpec(Base64.getDecoder().decode(privateKeyContent));
KeyFactory kf = KeyFactory.getInstance(Definitions.AuthProperty.RSA_KEY_FACTORY);
PrivateKey privKey = kf.generatePrivate(keySpecPKCS8);
String jwtAudUrl = System.getenv(Definitions.IamProperty.IAM_URL_KEY) + System.getenv(Definitions.IamProperty.JWT_AUD_URI_KEY);
String jwtToken = Jwts.builder()
.setAudience(jwtAudUrl)
.setSubject(serviceId)
.setIssuer(serviceId)
.setExpiration(new Date(new Date().getTime() + TimeUnit.MINUTES.toMillis(Definitions.AuthProperty.JWT_TOKEN_EXPIRY_IN_MINUTES)))
.signWith(privKey)
.compact();
Python：
import jwt
serviceID = "abc"
secret = '-----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----'

但是，我继续遇到这个错误：

The data may be in an incorrect format, it may be encrypted with an unsupported algorithm, or it may be an unsupported key type (e.g. EC curves with explicit parameters).', [_OpenSSLErrorWithText(code=503841036, lib=60, reason=524556, reason_text=b'error:1E08010C:DECODER routines::unsupported')])
有人可以帮我吗？
I am trying to convert this java code for generating JWT token in python.
String privateKeyContent = privateKey
.replaceAll(Definitions.ApiGeneral.LINE_BREAKER, "")
.replace(Definitions.AuthProperty.PRIVATE_KEY_START, "")

PKCS8EncodedKeySpec keySpecPKCS8 = new PKCS8EncodedKeySpec(Base64.getDecoder().decode(privateKeyContent));
KeyFactory kf = KeyFactory.getInstance(Definitions.AuthProperty.RSA_KEY_FACTORY);
PrivateKey privKey = kf.generatePrivate(keySpecPKCS8);
String jwtAudUrl = System.getenv(Definitions.IamProperty.IAM_URL_KEY) + System.getenv(Definitions.IamProperty.JWT_AUD_URI_KEY);
String jwtToken = Jwts.builder()
.setAudience(jwtAudUrl)
.setSubject(serviceId)

该问题在错误消息中精确确定：您的私钥格式不正确。 PEM编码的密钥由BASE64编码的主体组成，该主体包含每64个字符后的线路断开，并且在单独的线上包含一个标头和页脚。您的钥匙缺少线路断裂。
期望至少在单独的行上的标头和页脚，但对体内的线路断裂是可选的。因此，您必须传递键，例如这样：
或
使用此更改，代码有效（添加缺失的
iam_url和缺少的import> import语句）。请注意，Java代码中的
pkcs8encodedkeyspec期望PKCS＃8格式中编码的私有密钥，而在Python代码中，请应用PKCS＃1格式中的PPEM编码的私钥。通过删除标头，页脚和所有线路断裂，由PEM编码的密钥进行编码的键结果，以及将其余的基础64解码。 加密库支持
load_der_der_private_key（） ：
load_pem_private_key（） PKCS＃8和PKCS＃1格式。The issue is precisely identified in the error message: Your private key is incorrectly formatted. A PEM encoded key consists of the Base64 encoded body, which contains a line break after every 64 characters, and a header and footer on separate lines. Your key is missing the line breaks.
load_pem_private_key()expects at least header and footer on separate lines, but is tolerant about line breaks in the body, i.e. they are optional. So you have to pass your key e.g. like this:or
With this change the code works (after adding the missing
iam_urland the missingimportstatements).Note that
PKCS8EncodedKeySpecin the Java code expects a DER encoded private key in PKCS#8 format, while in the Python code a PEM encoded private key in PKCS#1 format is applied.A DER encoded key results from a PEM encoded key by removing header, footer and all line breaks, and Base64 decoding the rest. The Cryptography library supports the import of a DER encoded private key with
load_der_private_key():load_pem_private_key()andload_der_private_key()support both PKCS#8 and PKCS#1 format.
