Functions

func DataPath

func DataPath(host string) (string, error)

DataPath returns the Charm data path for the current user. This is where Charm keys are stored.

func FindAuthKeys

func FindAuthKeys(host string, keyType string) (pathsToKeys []string, err error)

FindAuthKeys looks in a user's XDG charm-dir for possible auth keys. If no keys are found we return an empty slice.

func RandomArt

func RandomArt(k charm.PublicKey) (string, error)

RandomArt returns the randomart for the given key.

func ValidateName

func ValidateName(name string) bool

ValidateName validates a given name.

Types

type Client

type Client struct {
	Config *Config
	// contains filtered or unexported fields
}

Client is the Charm client.

func NewClient

func NewClient(cfg *Config) (*Client, error)

NewClient creates a new Charm client.

func NewClientWithDefaults

func NewClientWithDefaults() (*Client, error)

func (*Client) Auth

func (cc *Client) Auth() (*charm.Auth, error)

Auth will authenticate a client and cache the result. It will return a proto.Auth with the JWT and encryption keys for a user.

func (*Client) AuthKeyPaths

func (cc *Client) AuthKeyPaths() []string

AuthKeyPaths returns the full file path of the Charm auth SSH keys.

func (*Client) AuthedJSONRequest

func (cc *Client) AuthedJSONRequest(method string, path string, reqBody interface{}, respBody interface{}) error

AuthedRequest sends an authorized JSON request to the Charm and Glow HTTP servers.

func (*Client) AuthedRawRequest

func (cc *Client) AuthedRawRequest(method string, path string) (*http.Response, error)

AuthedRawRequest sends an authorized request with no request body to the Charm and Glow HTTP servers.

func (*Client) AuthedRequest

func (cc *Client) AuthedRequest(method string, path string, headers http.Header, reqBody io.Reader) (*http.Response, error)

AuthedRequest sends an authorized request to the Charm and Glow HTTP servers.

func (*Client) AuthorizedKeys

func (cc *Client) AuthorizedKeys() (string, error)

AuthorizedKeys returns the keys linked to a user's account.

func (*Client) AuthorizedKeysWithMetadata

func (cc *Client) AuthorizedKeysWithMetadata() (*charm.Keys, error)

AuthorizedKeysWithMetadata fetches keys linked to a user's account, with metadata.

func (*Client) Bio

func (cc *Client) Bio() (*charm.User, error)

Bio returns the user's profile.

func (*Client) DefaultEncryptKey

func (cc *Client) DefaultEncryptKey() (*charm.EncryptKey, error)

DefaultEncryptKey returns the default EncryptKey for an authed user.

func (*Client) EncryptKeys

func (cc *Client) EncryptKeys() ([]*charm.EncryptKey, error)

EncryptKeys returns all of the symmetric encrypt keys for the authed user.

func (*Client) ID

func (cc *Client) ID() (string, error)

ID returns the user's ID.

func (*Client) InvalidateAuth

func (cc *Client) InvalidateAuth()

InvalidateAuth clears the JWT auth cache, forcing subsequent Auth() to fetch a new JWT from the server.

func (*Client) JWT

func (cc *Client) JWT(aud ...string) (string, error)

JWT returns a JSON web token for the user.

func (*Client) KeyForID

func (cc *Client) KeyForID(gid string) (*charm.EncryptKey, error)

KeyForID returns the decrypted EncryptKey for a given key ID.

func (*Client) Link

func (cc *Client) Link(lh charm.LinkHandler, code string) error

Link joins in on a linking session initiated by LinkGen.

func (*Client) LinkGen

func (cc *Client) LinkGen(lh charm.LinkHandler) error

LinkGen initiates a linking session.

func (*Client) News

func (cc *Client) News(id string) (*charm.News, error)

func (*Client) NewsList

func (cc *Client) NewsList(tags []string, page int) ([]*charm.News, error)

func (*Client) SetName

func (cc *Client) SetName(name string) (*charm.User, error)

SetName sets the account's username.

func (*Client) SyncEncryptKeys

func (cc *Client) SyncEncryptKeys() error

SyncEncryptKeys re-encodes all of the encrypt keys associated for this public key with all other linked public keys.

func (*Client) UnlinkAuthorizedKey

func (cc *Client) UnlinkAuthorizedKey(key string) error

UnlinkAuthorizedKey removes an authorized key from the user's Charm account.
