converting string and decimal values from Host app to hex for APDU..

843851Mar 30 2005 — edited Oct 26 2005

Hi,
I am writing a host appliication for a Java Card applet in which the user types in the PIN value to be checked by the card. I am stuck on how to convert "a1b2c3" that the user types in into a series of bytes for my APDU data to be sent to the card.
I know from conversion charts that the conversion needs to result in

a - 0x61
1 - 0x01
b - 0x62
2 - 0x02
c - 0x63
3 - 0x03

Can anyone point me in the direction of how to take care of this. I am writing my host app using Java and JCOP offcard tools.

Thanks in advance,
Ann
