Overview ¶
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.

Functions ¶
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 have the public certificate and the private key encoded. The private key must be encoded in PKCS8 (not PKCS1). This is usally denoted by the section "PRIVATE KEY" (instead of PKCS1's "RSA PRIVATE KEY"). If a PEM block is encoded and password is not an empty string, it attempts to decrypt the PEM blocks using the password. This will return multiple x509 certificates, though this use case should have a single cert. Multiple certs are due to certificate chaining for use cases like TLS that sign from root to leaf.
Types ¶
type AcquireTokenByAuthCodeOption ¶
type AcquireTokenByAuthCodeOption func(a *AcquireTokenByAuthCodeOptions)
AcquireTokenByAuthCodeOption changes options inside AcquireTokenByAuthCodeOptions used in .AcquireTokenByAuthCode().
func WithChallenge ¶
func WithChallenge(challenge string) AcquireTokenByAuthCodeOption
WithChallenge allows you to provide a challenge for the .AcquireTokenByAuthCode() call.
type AcquireTokenByAuthCodeOptions ¶
type AcquireTokenByAuthCodeOptions struct {
Challenge string
}
AcquireTokenByAuthCodeOptions contains the optional parameters used to acquire an access token using the authorization code flow.
type AcquireTokenSilentOption ¶
type AcquireTokenSilentOption func(a *AcquireTokenSilentOptions)
AcquireTokenSilentOption changes options inside AcquireTokenSilentOptions used in .AcquireTokenSilent().
func WithSilentAccount ¶
func WithSilentAccount(account Account) AcquireTokenSilentOption
WithSilentAccount uses the passed account during an AcquireTokenSilent() call.
type AcquireTokenSilentOptions ¶
type AcquireTokenSilentOptions struct {
// Account represents the account to use. To set, use the WithSilentAccount() option.
Account Account
}
AcquireTokenSilentOptions are all the optional settings to an AcquireTokenSilent() call. These are set by using various AcquireTokenSilentOption functions.
type AuthResult ¶
type AuthResult = base.AuthResult
AuthResult contains the results of one token acquisition operation. For details see https://aka.ms/msal-net-authenticationresult
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client is a representation of authentication client for confidential applications as defined in the package doc. A new Client should be created PER SERVICE USER. For more information, visit https://docs.microsoft.com/azure/active-directory/develop/msal-client-applications
func New ¶
func New(clientID string, cred Credential, options ...Option) (Client, error)
New is the constructor for Client. userID is the unique identifier of the user this client will store credentials for (a Client is per user). clientID is the Azure clientID and cred is the type of credential to use.
func (Client) Account ¶
Account gets the account in the token cache with the specified homeAccountID
func (Client) AcquireTokenByAuthCode ¶
func (cca Client) AcquireTokenByAuthCode(ctx context.Context, code string, redirectURI string, scopes []string, options ...AcquireTokenByAuthCodeOption) (AuthResult, error)
AcquireTokenByAuthCode is a request to acquire a security token from the authority, using an authorization code. The specified redirect URI must be the same URI that was used when the authorization code was requested.
func (Client) AcquireTokenByCredential ¶
func (cca Client) AcquireTokenByCredential(ctx context.Context, scopes []string) (AuthResult, error)
AcquireTokenByCredential acquires a security token from the authority, using the client credentials grant.
func (Client) AcquireTokenSilent ¶
func (cca Client) AcquireTokenSilent(ctx context.Context, scopes []string, options ...AcquireTokenSilentOption) (AuthResult, error)
AcquireTokenSilent acquires a token from either the cache or using a refresh token.
type Credential ¶
type Credential struct {
// contains filtered or unexported fields
}
Credential represents the credential used in confidential client flows.
func NewCredFromCert ¶
func NewCredFromCert(cert *x509.Certificate, key crypto.PrivateKey) Credential
NewCredFromCert creates a Credential from an x509.Certificate and a PKCS8 DER encoded private key. CertFromPEM() can be used to get these values from a PEM file storing a PKCS8 private key.
Example (Pem) ¶
b, err := ioutil.ReadFile("key.pem")
if err != nil {
log.Fatal(err)
}
// This extracts our public certificates and privage key from the PEM file.
// The private key must be in PKCS8 format. If it is encrypted, the second argument
// must be password to decode.
certs, priv, err := CertFromPEM(b, "")
if err != nil {
log.Fatal(err)
}
// PEM files can have multiple certs. This is usually for certificate chaining where roots
// sign to leafs. Usefule for TLS, not for this use case.
if len(certs) > 1 {
log.Fatal("too many certificates in PEM file")
}
cred := NewCredFromCert(certs[0], priv)
if err != nil {
log.Fatal(err)
}
fmt.Println(cred) // Simply here so cred is used, otherwise won't compile.
Output:
func NewCredFromSecret ¶
func NewCredFromSecret(secret string) (Credential, error)
NewCredFromSecret creates a Credential from a secret.
type Option ¶
type Option func(o *Options)
Option is an optional argument to New().
func WithAccessor ¶
func WithAccessor(accessor cache.ExportReplace) Option
WithAccessor provides a cache accessor that will read and write to some externally managed cache that may or may not be shared with other applications.
func WithAuthority ¶
WithAuthority allows you to provide a custom authority for use in the client.
func WithHTTPClient ¶
func WithHTTPClient(httpClient ops.HTTPClient) Option
WithHTTPClient allows for a custom HTTP client to be set.
type Options ¶
type Options struct {
// Accessor controls cache persistence.
// By default there is no cache persistence. This can be set using the WithAccessor() option.
Accessor cache.ExportReplace
// The host of the Azure Active Directory authority.
// The default is https://login.microsoftonline.com/common. This can be changed using the
// WithAuthority() option.
Authority string
// The HTTP client used for making requests.
// It defaults to a shared http.Client.
HTTPClient ops.HTTPClient
// SendX5C specifies if x5c claim(public key of the certificate) should be sent to STS.
SendX5C bool
}
Options are optional settings for New(). These options are set using various functions returning Option calls.
