Without Libgcrypt 1.5 is was not possible to use ECC keys. ECC is
major new feature and thus it does not make sense to allow building
with an older Libgcrypt without supporting ECC.
Also fixed a few missing prototypes.
This is not a part of pin pad support series of mine.
As I found the bug while I am preparing the patches, I report this.
As CCID protocol is little endian, wLangId of US English = 0x0409
is represented as two bytes of 0x09 then 0x04.
It is really confusing that the code like following is floating
around:
pin_verify -> wLangId = HOST_TO_CCID_16(0x0904);
But, it is 0x0409 (not 0x0904). It is defined in the documentation:
http://www.usb.org/developers/docs/USB_LANGIDs.pdf
and origin of this table is Microsoft. We can see it at:
http://msdn.microsoft.com/en-us/library/bb165625%28VS.80%29.aspx
Yes, it would be better not to hard-code 0x0409. It would be better
to try current locale of the user, or to use the first entry of string
descriptor. I don't have time to implement such a thing...
This was a regression in 2.1 introduced due to having the agent do the
signing in contrast to the old "SCD PKSIGN" command which accesses the
scdaemon directly and passed the hash algorithm. The hash algorithm
is used by app-openpgp.c only for a sanity check.
Using "gpgsm --genkey" allows the creation of a self-signed
certificate via a new prompt.
Using "gpgsm --genkey --batch" should allow the creation of arbitrary
certificates controlled by a parameter file. An example parameter file
is
Key-Type: RSA
Key-Length: 1024
Key-Grip: 2C50DC6101C10C9C643E315FE3EADCCBC24F4BEA
Key-Usage: sign, encrypt
Serial: random
Name-DN: CN=some test key
Name-Email: foo@example.org
Name-Email: bar@exmaple.org
Hash-Algo: SHA384
not-after: 2038-01-16 12:44
This creates a self-signed X.509 certificate using the key given by
the keygrip and using SHA-384 as hash algorithm. The keyword
signing-key can be used to sign the certificate with a different key.
See sm/certreggen.c for details.
This solves a problem where ccid was used, the card unplugged and then
scdaemon tries to find a new (plugged in) reader and thus will
eventually try PC/SC over and over again.
Also added an explicit --kill command to gpgconf.
The import test imports the keys as needed and because they are
passphrase protected we now need a pinentry script to convey the
passphrase to gpg-agent.
The basic network code from http.c is used for finger. This keeps the
network related code at one place and we are able to use the somewhat
matured code form http.c. Unfortunately I had to enhance the http
code for more robustness and probably introduced new bugs.
Test this code using
gpg --fetch-key finger:wk@g10code.com
(I might be the last user of finger ;-)
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
To avoid checking in trailing scripts the autogen.sh script now
enables the standard pre-commit hook, which check for this.
Add a cleanpo filter if not yet set. This works with together with
po/.gitattributes.
DECRYPTION_INFO <mdc_method> <sym_algo>
Print information about the symmetric encryption algorithm and
the MDC method. This will be emitted even if the decryption
fails.
Wrote the ChangeLog 2011-01-13 entry for Andrey's orginal work modulo
the cleanups I did in the last week. Adjusted my own ChangeLog
entries to be consistent with that entry.
Nuked quite some trailing spaces; again sorry for that, I will better
take care of not saving them in the future. "git diff -b" is useful
to read the actual changes ;-).
The ECC-INTEGRATION-2-1 branch can be closed now.
Import and export of secret keys does now work. Encryption has been
fixed to be compatible with the sample messages.
This version tests for new Libgcrypt function and thus needs to be
build with a new Libgcrypt installed.
Quite some changes were needed but in the end we have less code than
before. Instead of trying to do everything with MPIs and pass them
back and forth between Libgcrypt and GnuPG, we know use the
S-expression based interface and make heavy use of our opaque MPI
feature.
Encryption, decryption, signing and verification work with
self-generared keys.
Import and export does not yet work; thus it was not possible to check
the test keys at https://sites.google.com/site/brainhub/pgpecckeys .
