RNG, AES support in VIA C3

[Joel Carnat <joel%carnat.net@localhost>]

Hello,

The cpuctl command outputed:
cpu0: VIA C3 Nehemiah (686-class), 1002.33 MHz, id 0x698
cpu0: features 0x381b83f<FPU,VME,DE,PSE,TSC,MSR,SEP,MTRR>
cpu0: features 0x381b83f<PGE,CMOV,PAT,MMX>
cpu0: features 0x381b83f<FXSR,SSE>
cpu0: padlock features 0xdd<RNG,AES>

Does this mean than random number generation and encryption operations are done 
via the hardware ?
Would encryption for (Open)VPN and HTTPS be done by the hardware too ?
Does using the hardware only relies on the OpenSSL implementation or is the 
software involved too ? Like Apache would be OK but lighttpd would not ?

TIA,
   Jo
