In the event that the user has any complaint and / or claim, Coloriuris offers a complaint channel expressly conceived for this purpose:





Time stamping is a method to prove that a data set (datum) existed before a given time and furthermore that no bit of this data has been modified since.

In addition, time stamping provides additional value to the use of electronic signature, since this one alone does not provide any information about the moment of creation of the signature. The electronic certificates used by the algorithm of the electronic signature has a period of validity and therefore, the signature without the digital date, after the validity of the certificate, can always be rejected.

To associate the data with a specific moment in time, it is necessary to use a Time Stamp Authority (TSA) as a Trusted Service Provider.


The TSA centralizes the issue of temporary certificates. The role of this entity will be to produce, store, verify and renew the temporary certificates. The TSA will be a Trusted Services Provider (TSP), being its signature on the temporary certificate sufficient proof to prove its validity.

This protocol allows time stamping on any type of digital information, and protects the confidentiality of the data dated.

The user of the time stamp service must be holder of a certificate issued by a Qualified Trusted Service Provider.

The TSA makes use of a certificate issued exclusively for time stamping purposes.

Time Stamp Application

Once the user has a X.509 certificate and its corresponding private key will be able to make time stamp requests. The process for making a time stamp request is as follows:

1. The user selects the electronic file from which is requested the TSA time stamp.

2. The client application compiles a summary (hash) of the contents of that file.

3. The user selects the service policy preferred, the reference number, the version…

4. The client application composes an electronic time stamp request and sends it via HTTPS.

Time stamping response

Once the TSA has received the time stamp request and has accepted it, this will proceed to return the time stamp response or Response via HTTPS to the client application. This Response is an object that contains a mandatory field, which is the state of the operation, and in the case that it was satisfactorily implemented, it contains a CMS Signed-Data object, which is the signature of the object that contains all the information of the time certificate. The client may choose to directly store that Response, validating it previously or he may choose to perform verification of it too, in case there have been no errors. For that:

1. The client application recomposes the Response object, extracting the state of the operation, and if it is GRANTED, the CMS Signed-Data object can be extracted too.

2. The client application recomposes the CMS Signed-Data object, extracting the signed data and verifying that the signature is correct, making use of the TSA certificate included in the CMS object.

3. The certificates included in the CMS object are obtained and «path validation» is done.

4. If the client has selected it, the OCSP verification (On-line Certificate Status Protocol) of the certificates is made, in order to check the revocation status of those certificates.

5. The client application will obtain the data of the time stamping of the token.
