* scd: Fix for large ECC keys.NIIBE Yutaka2017-09-111-8/+32

* scd: Convey the correct length for LeWerner Koch2017-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | * scd/app-openpgp.c (determine_rsa_response): Round bits up. -- Co-authored-by: Arnaud Fontaine <[email protected]> Arnaud wrote: Actually, when the incorrect expected response length (i.e. Le field) is transmitted to the card, the card's answer is missing a byte (i.e. ... 6101) so an additional command has to be sent to the card to retrieve the last byte. Using the correct length avoids to send the additional command to retrieve the missing byte, when the computed length is wrong. Note that an value of 65537 for E is pretty standard and thus we can avoid the 6101 return code inmost cases. Signed-off-by: Werner Koch <[email protected]>
