Methods
- appendHmac() : string
- Appends a hash (HMAC) to a given string and additional secret and returns the result
- hmac() : string
- Returns a proper HMAC with a length of 40 (HMAC-SHA-1) on a given input string, additional secret and the secret TYPO3 encryption key.
- validateAndStripHmac() : string
- Tests if the last 40 characters of a given string $string and $additionalSecret matches the HMAC of the rest of the string and, if true, returns the string without the HMAC. In case of an invalid HMAC string an exception is thrown.
- validateHmac() : bool
- Returns, if a string $string and $additionalSecret matches the HMAC given by $hash.
