英文:
Unable to Read RSA Key
问题
我需要从文件中读取一个RSA私钥来对JWT进行签名。我正在使用openssl生成私钥。在解密私钥时出现了长度过大的错误。
openssl genrsa -des3 -out jwt-private.pem 2048

出现错误，长度过大。

Getting error as length too large

密钥上标明它已加密，Proc-Type: 4,ENCRYPTED，因此您必须使用生成密钥时输入的密码先对其进行解密。
data, _ := pem.Decode([]byte(pembytes))
if data == nil {
log.Fatalf("bad key data, not PEM-encoded?")
}
pemBytes, err := x509.DecryptPEMBlock(data, []byte("somePassword"))
if err != nil {
log.Fatalf("failed to decrypt block: %v", err)
}
privateKeyImported, err := x509.ParsePKCS1PrivateKey(pemBytes)
if err != nil {
log.Fatalf("failed to parse private key: %v", err)
}
英文:
The key says it's encrypted, Proc-Type: 4,ENCRYPTED so you must first decrypt it with the password you entered when generating the key.
data, _ := pem.Decode([]byte(pembytes))
if data == nil {
log.Fatalf("bad key data, not PEM-encoded?")
}
pemBytes, err := x509.DecryptPEMBlock(data, []byte("somePassword"))
if err != nil {
log.Fatalf("failed to decrypt block: %v", err)
}
privateKeyImported, err := x509.ParsePKCS1PrivateKey(pemBytes)
if err != nil {
log.Fatalf("failed to parse private key: %v", err)
}
