Aici te inseli pentru ca compari mere cu pere. Cand te referi la 128 te referi la cheie simetrica, iar cand vorbesti de 2048 vorbesti de cheie asimetrica.Postat în original de sergiuliano
"As of 2003 RSA Security claims that 1024-bit RSA keys are equivalent in strength to 80-bit symmetric keys, 2048-bit RSA keys to 112-bit symmetric keys and 3072-bit RSA keys to 128-bit symmetric keys. RSA claims that 1024-bit keys are likely to become crackable some time between 2006 and 2010 and that 2048-bit keys are sufficient until 2030."
