The key length is limited by the card firmware. For each crypto operation, a data block with the same size as the key needs to be transferred to the card, which needs to have buffer space available for the data. While the crypto processor itself can handle 4096 bit keys, the code running on the card that implements the card "file system" and prods the crypto unit to work cannot handle that (and a bug in the decryption code also precludes using 3072 bit "encryption" keys). > Is there any way of transferring my existing 4096 bit keys to the card. > Generating new 3072 bit keys worked fine but it would be a lot better if I > could stick to my 4096 keys. You can use the card for subkeys only. Simon _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
