CryptoProvider class

  • Reference
Package:
@azure/msal-node

This class implements MSAL node's crypto interface, which allows it to perform base64 encoding and decoding, generating cryptographically random GUIDs and implementing Proof Key for Code Exchange specs for the OAuth Authorization Code Flow using PKCE (rfc here: https://tools.ietf.org/html/rfc7636).

Constructors

CryptoProvider()

Methods

base64Decode(string)

Decodes input string from base64.
base64Encode(string)

Encodes input string to base64.
clearKeystore()

Removes all cryptographic keys from Keystore
createNewGuid()

Creates a new random GUID - used to populate state and nonce.
generatePkceCodes()

Generates PKCE codes used in Authorization Code Flow.
getPublicKeyThumbprint()

Generates a keypair, stores it and returns a thumbprint - not yet implemented for node
hashString(string)

Returns the SHA-256 hash of an input string
removeTokenBindingKey()

Removes cryptographic keypair from key store matching the keyId passed in
signJwt()

Signs the given object as a jwt payload with private key retrieved by given kid - currently not implemented for node
