I'm trying to create a jwt token using ES256 algorithm but I can't parse my private key
php editor Strawberry is trying to create a jwt token using the ES256 algorithm, but encounters a problem parsing the private key. This is a common problem and may be caused by the private key being incorrect or the format not meeting the requirements. To solve this problem, you first need to ensure that the private key is correct and meets the requirements of the ES256 algorithm. If the private key was obtained from elsewhere, you can try to regenerate a new private key. In addition, make sure the private key is in the correct format. You can use the openssl command line tool to verify the private key format. If the private key is in the correct format but still cannot be parsed, it may be due to other reasons, such as permission issues or environment configuration issues. Before solving this problem, you can first check the relevant permissions and configuration to make sure there are no omissions or errors.
Question content
This is my golang code trying to create a JWT token
package main import ( "encoding/pem" "fmt" "time" "github.com/dgrijalva/jwt-go" ) func main() { // Sample PEM-encoded private key pemKey := `-----BEGIN EC PRIVATE KEY-----MHcCAQEEIAh5qA3rmqQQuu0vbKV/+zouz/y/Iy2pLpIcWUSyImSwoAoGCCqGSM49AwEHoUQDQgAEYD54V/vp+54P9DXarYqx4MPcm+HKRIQzNasYSoRQHQ/6S6Ps8tpMcT+KvIIC8W/e9k0W7Cm72M1P9jU7SLf/vg==-----END EC PRIVATE KEY-----` // Convert the PEM-encoded private key to a byte slice pemBytes, _ := pem.Decode([]byte(pemKey)) // // Parse and decode the private key key, err := jwt.ParseECPrivateKeyFromPEM(pemBytes.Bytes) if err != nil { fmt.Println("Error parsing private key:", err) return } uAccessToken := jwt.NewWithClaims(jwt.SigningMethodES256, jwt.MapClaims{ "iss": "issuer", "sub": "access token", "exp": time.Now().Add(time.Minute * 20).Unix(), }) AccessToken, err := uAccessToken.SignedString(key); if err != nil { fmt.Println("Error signing token:", err) return } // // You now have the ECDSA private key available in the 'key' variable fmt.Println("ECDSA Private Key:", AccessToken) }
But every time I try to create a token I get this error:
<code> Error parsing private key: Invalid Key: Key must be PEM encoded PKCS1 or PKCS8 private key </code>
Can anyone suggest what's going wrong here?
I'm trying to create a JWT using the ES256 algorithm where I need the private key. But somehow I got the error.
Solution
Requires two fixes
1 - Comment/Remove pem.Decode()
It requires the raw pem key in bytes.
2-Key string in single line change key string

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
