It is important that the keys assigned to tokens are sufficiently randomised and secured that they can serve as identifying a unique user session. Implementations of
TokenServiceare free to use encryption or encoding strategies of their choice. It is strongly recommended that keys are of sufficient length to balance safety against persistence cost. In relation to persistence cost, it is strongly recommended that returned keys are small enough for encoding in a cookie.
All Methods Instance Methods Abstract Methods Modifier and Type Method Description
getExtendedInformation()Obtains the extended information associated within the token, which was presented when the token was first created.
getKey()Obtains the randomised, secure key assigned to this token.
getKeyCreationTime()The time the token key was initially created is available from this method.
java.lang.String getKey()Obtains the randomised, secure key assigned to this token. Presentation of this token to
TokenServicewill always return a
Tokenthat is equal to the original
Tokenissued for that key.
- a key with appropriate randomness and security.
long getKeyCreationTime()The time the token key was initially created is available from this method. Note that a given token must never have this creation time changed. If necessary, a new token can be requested from the
TokenServiceto replace the original token.
- the time this token key was created, in the same format as specified by
- the user-specified extended information, if any
