We would like to inform our customers that on April 15, 2026, the timestamp generation algorithm will change from RSA 2048-bit to ECDSA 256-bit.

This change is necessary in order to comply with ETSI TS 119 312 v. 1.5.1 https://www.etsi.org/deliver/etsi_ts/119300_119399/119312/01.05.01_60/ts_119312v010501p.pdf and the implementing acts
