The Department of Economics has informed us that a change will soon be made in the TLS protocol of the PSCP and RPC domains (among others).

This modification is motivated by the mitigation of the obsolescence of the TLS 1.0 and 1.1 protocols, in addition to the SSL.

The currently recommended protocols will be added so that the configuration will be as follows:

TLS1.2 and TLS1.3

AES256 (RSA_WITH_AES_256_CBC_SHA)

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA256

TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256

From this change, browsers compatible with the use of e-Procurement services must be updated, at least, to the versions shown in green in the image below:
