        # OpenSSL::Timestamp::TokenInfo.algorithm

(from ruby core)
### Implementation from TokenInfo
---
    token_info.algorithm -> string or nil

---

Returns the 'short name' of the object identifier representing the
algorithm that was used to derive the message imprint digest. For valid
timestamps, this is the same value that was already given in the
Request. If status is GRANTED or GRANTED_WITH_MODS, this is never `nil`.

### Example:
    algo = token_info.algorithm
    puts algo                -> "SHA1"
