JWTSigner

public struct JWTSigner

A struct that will be used to sign the JWT Header and Claims and generate a signed JWT. For RSA and ECDSA, the provided key should be a .utf8 encoded PEM String.

Usage Example:

let pemString = """

  • Initialize a JWTSigner using the RSA 256 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func rs256(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the RSA 384 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func rs384(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the RSA 512 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func rs512(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the RSA-PSS 256 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func ps256(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the RSA-PSS 384 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func ps384(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the RSA-PSS 512 bits algorithm and the provided privateKey. This signer requires at least a 2048 bit RSA key.

    Declaration

    Swift

    public static func ps512(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with a BEGIN RSA PRIVATE KEY header.

  • Initialize a JWTSigner using the HMAC 256 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func hs256(key: Data) -> JWTSigner

    Parameters

    key

    The HMAC symmetric password data.

  • Initialize a JWTSigner using the HMAC 384 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func hs384(key: Data) -> JWTSigner

    Parameters

    key

    The HMAC symmetric password data.

  • Initialize a JWTSigner using the HMAC 512 bits algorithm and the provided privateKey.

    Declaration

    Swift

    public static func hs512(key: Data) -> JWTSigner

    Parameters

    key

    The HMAC symmetric password data.

  • Initialize a JWTSigner using the ECDSA SHA256 algorithm and the provided privateKey.

    Declaration

    Swift

    @available(OSX 10.13, iOS 11, tvOS 11.0, watchOS 4.0, *)
public static func es256(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with either a BEGIN EC PRIVATE KEY or BEGIN PRIVATE KEY header.

  • Initialize a JWTSigner using the ECDSA SHA384 algorithm and the provided privateKey.

    Declaration

    Swift

    @available(OSX 10.13, iOS 11, tvOS 11.0, watchOS 4.0, *)
public static func es384(privateKey: Data) -> JWTSigner

public static func es512(privateKey: Data) -> JWTSigner

    Parameters

    privateKey

    The UTF8 encoded PEM private key, with either a BEGIN EC PRIVATE KEY or BEGIN PRIVATE KEY header.

  • Initialize a JWTSigner that will not sign the JWT. This is equivelent to using the none alg header.
