We have a Windows application that automatically generates a key pair on first startup (no passphrase), then sends its public key to a server. It exports its public key to a file with a command like this:
gpg --output client-key.gpg --export -a ID49C207DF I recently got an error message caused by the keyfile it created exceeding a 10 KB threshold in the application code. It is normally 2 KB or 3 KB, but in this case it was 25KB. Its size apparently jumped suddenly rather than growing slowly, or it would have errored out at 11 KB rather than at 25 KB. The extra-large key file has typical GPG headers and footers, but a lot more data between them than usual. Renaming the gnupg directory (which forces it to generate a new key pair) resolved the issue for now, but I would like to know what might have gone wrong to make the public key so large. In both cases, the info about the keys looks normal, something like this: $ gpg --list-keys C:/Documents and Settings/steve.strobel/Application Data/gnupg\pubring.gpg -------------------------------------------------------------------------- pub 2048R/49C207DF 2014-03-07 uid ID49C207DF (N/A) <id49c20...@vtrunk.net> uid IDLINKTDS <idlink...@vtrunk.net> I would be glad to send the keyring file if that would make troubleshooting easier (the keys are not valuable). Thanks for any pointers.
