nach der Bestellung gedruckt Neuware - Printed after ordering - L'algorithme de signature numérique à courbe elliptique (ECDSA) se compose de deux modules : l'un est l'algorithme de signature utilisé par un signataire et le second est l'algorithme de vérification utilisé par le public pour vérifier l'identité du signataire. Une personne qui souhaite signer un message numériquement utilise l'algorithme de signature, qui établit d'abord un condensé du message (hachage) à l'aide d'une fonction de hachage appropriée (SHA-1), puis le condensé du message est crypté à l'aide de la clé privée du signataire. Le condensé crypté du message est la 'signature numérique' de l'expéditeur sur ce message. N'importe qui peut vérifier si cette 'signature numérique' est authentique ou non en utilisant un algorithme de vérification. Dans un premier temps, un condensé du message du signataire est créé à l'aide de la fonction de hachage identique (SHA-1). Le vérificateur décrypte ensuite le résultat chiffré du hachage à l'aide de la clé publique du signataire. Si le résultat du hachage chiffré et le condensé du message créé par le vérificateur sont identiques, l'authenticité du signataire est prouvée. Pendant la durée du projet, un programme d'application Java a été écrit dans lequel la fonctionnalité ECDSA de signature et de vérification est fournie.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
