confidential Package
import "github.com/AzureAD/microsoft-authentication-library-for-go/apps/confidential"
Package confidential provides a client for authentication of "confidential" applications. A "confidential" application is defined as an app that run on servers. They are considered difficult to access and for that reason capable of keeping an application secret. Confidential clients can hold configuration-time secrets.
func AutoDetectRegion
func AutoDetectRegion() string
AutoDetectRegion instructs MSAL Go to auto detect region for Azure regional token service.
func CertFromPEM
func CertFromPEM(pemData []byte, password string) ([]*x509.Certificate, crypto.PrivateKey, error)
CertFromPEM converts a PEM file (.pem or .key) for use with [NewCredFromCert]. The file must contain the public certificate and the private key. If a PEM block is encrypted and password is not an empty string, it attempts to decrypt the PEM blocks using the password. Multiple certs are due to certificate chaining for use cases like TLS that sign from root to leaf.

type Credential
Credential represents the credential used in confidential client flows.
type Credential struct {
// contains filtered or unexported fields
}
func NewCredFromAssertionCallback
func NewCredFromAssertionCallback(callback func(context.Context, AssertionRequestOptions) (string, error)) Credential
NewCredFromAssertionCallback creates a Credential that invokes a callback to get assertions authenticating the application. The callback must be thread safe.

package main
import (
"fmt"
"log"
"os"
"github.com/AzureAD/microsoft-authentication-library-for-go/apps/confidential"
)
func main() {
b, err := os.ReadFile("key.pem")
if err != nil {
log.Fatal(err)
}
// This extracts our public certificates and private key from the PEM file. If it is
// encrypted, the second argument must be password to decode.
certs, priv, err := confidential.CertFromPEM(b, "")
if err != nil {
log.Fatal(err)
}
cred, err := confidential.NewCredFromCert(certs, priv)
if err != nil {

NewCredFromSecret creates a Credential from a secret.
func NewCredFromTokenProvider
func NewCredFromTokenProvider(provider func(context.Context, TokenProviderParameters) (TokenProviderResult, error)) Credential
NewCredFromTokenProvider creates a Credential from a function that provides access tokens. The function must be concurrency safe. This is intended only to allow the Azure SDK to cache MSI tokens. It isn't useful to applications in general because the token provider must implement all authentication logic.
type Option
Option is an optional argument to New().
type Option func(o *clientOptions)
func WithAzureRegion
func WithAzureRegion(val string) Option
WithAzureRegion sets the region(preferred) or Confidential.AutoDetectRegion() for auto detecting region. Region names as defined on the Azure site. See https://aka.ms/region-map for more details on region names. The region value should be short region name for the region where the service is deployed. For example "centralus" is short name for region Central US. Not all auth flows can use the regional token service. Service To Service (client credential flow) tokens can be obtained from the regional service. Requires configuration at the tenant level. Auto-detection works on a limited number of Azure artifacts (VMs, Azure functions). If auto-detection fails, the non-regional endpoint will be used. If an invalid region name is provided, the non-regional endpoint MIGHT be used or the token request MIGHT fail.
func WithCache
func WithCache(accessor cache.ExportReplace) Option
WithCache provides an accessor that will read and write authentication data to an externally managed cache.
func WithClientCapabilities
func WithClientCapabilities(capabilities []string) Option
