Commissioned by Estonian Information System Authority (RIA), a new study has been completed on the lifecycle of encryption algorithms. According to Toomas Vaks, Deputy Director-General of RIA, it is important to abolish 1024-bit keys as soon as possible everywhere. For the next five years, 2048-bit keys and, in the long-term, 3072-bit keys at a minimum should be used.
