Hi!

I need help with this algorithm:

  1. token = SHA1(nonce + SHA1(password))

nonce : binary, hex or string ?


+ : sum? concatenation?


Thanx

nonce is string, you can see it here https://my.zipato.com/zipato-web/api/#!/user/initialize_get_1

+ is concatenation

There are many variations of this technology, but the hardware token One-Time Password algorithm is a particularly slick system. It uses an algorithm that updates a counter every time a user requests a HOTP. The updated counter is used to generate a new password, and each user will be given a different, unique value to use as a passcode. The algorithm is based on a secret key, which is passed between the user and an authentication server. The value is then encrypted to produce a unique and tamper-proof string of characters.

What is Token Bucket Algorithm? The token bucket algorithm is used in packet-switched and computer networks to ensure that data transmission in packets does not cross its bandwidth. The packets are thrown into the bucket. It holds packets generated at regular intervals of time.

Token Bucket Algorithm: What is it? In order to prevent data transmission in packets from exceeding its bandwidth, the token bucket mechanism is employed in packet-switched and computer networks. The bucket is filled with the packets. It keeps packets that are produced at regular intervals. monkey mart
