The difference is that, instead of a jumble, the result is a grammatically-valid short phrase.

TripphrasesДЄ tripphrase functions similarly to a tripcode, in that the user enters a password which is hashed into a unique identifier.

How to crack a tripcode verification#

Tripcodes are useless for casual verification of identity. Comparing two jumbles letter-by-letter is a slow and boring process. Tripcodes allow someone to verify that two messages were written by the same person, but the verification must be deliberate and intentional. When reading casually, people try to not even see them - a meaningless jumble interrupts reading flow. People don't remember meaningless jumbles. The strongest crypto-hash invented will do you no good if nobody bothers to verify it.ДЄ tripcode is a meaningless jumble of letters and numbers. Problem 2: Nobody looks at tripcodes.ДЄ secondary problem with tripcodes is that almost nobody reads them. Their only social function is to serve as a badge that the user is paranoid about being impersonated. The user can't choose them to convey his personality. Unlike usernames (and on other messageboards, avatars and signatures), tripcodes serve no communicative purpose. Why? Probably because they just look stupid. But even in the less staunchly anonymous areas, tripcodes invite some amount of derision. There are areas of 4chan where anonymity is deeply ingrained in the culture, and in these cases, no form of authentication would be socially accepted. All of the crypto-bits on the internet will do you no good if they're not actually used. The primary problem with tripcodes is that almost nobody uses them, and the few that do are derided. The real problems with tripcodes have nothing to do with bits and keyspaces, and everything to do with people.

(USER WAS BANNED FOR THIS POST) (By most measures, 4chan moderators are more vigilant and responsive than the average police force.) Likewise, if someone is assuming others' identities on 4chan, the moderators will catch them and ban them. If someone breaks into your house, the police will catch them and throw them in jail. A tripcode functions like the lock on your front door: it only needs to keep out casually mischievious people, because there are social mechanisms to take care of people who circumvent it.

A number of 'secure tripcode' schemes have been proposed to add cryptographic strength in various ways. It is commonly said that the problem with tripcodes is that they are insufficiently cryptographically secure, providing only a 54-bit keyspace, and are thus vulnerable to brute-force attack (systematic guessing). If two messages have the same tripcode, readers can be reasonably sure that they were written by the same person.
