Functions

func Fingerprint

func Fingerprint(rawPubKey string) (string, error)

Fingerprint will attempt to generate a fingerprint from the provided rawPubKey The fingerprint is simply the URL safe, Base64 encoded sha256 hash of the public key

func GenerateDeterministicUUID

func GenerateDeterministicUUID(key, title, namespace string) (string, error)

GenerateDeterministicUUID creates a deterministic (version 5) uuid from the provided key and title

func ParseExpiration

func ParseExpiration(expirationRequest string) *time.Time

ParseExpiration converts common expiration times used on our frontend into actual time periods our post reaper will leverage to expire posts.

func ValidateSignature

func ValidateSignature(rawPubKey string, base64EncodedSignature string, message string) error

ValidateSignature ensures that the signature provided in base64EncodedSignature is valid, i.e. it was signed by the provided rawPubKey and contains the provided message

Types
