I noticed a strange problem which occurred now three or maybe four
times, all under different circumstances.
I was using my Openpgp Smartcard to encrypt a file (size about 1.4 MB)
to someone else and to my key as well.
When I wanted to access the very same encrypted file to check if I was
able to decrypt it, I got this error:
gpg: block_filter 00B36A38: read error (size=9277,a->size=9277)
gpg: Problem reading source (16560 bytes remaining)
gpg: handle plaintext failed: file read error
gpg: mdc_packet with invalid encoding
gpg: decryption failed: invalid packet
gpg: block_filter: pending bytes!
It decrypted parts of the file, but stopped eventually, so the file
isn't completely decrypted.
I had the same problem with encrypted attachments I received from other
people who encrypted only against my public key. It's weird. However, I
also encrypted large files with success, so this is a sparse problem.
Does anyone have an idea what the problem could be? Is my smartcard
Using gpg 1.4.7 on Windows, same problem occurs with gpg 1.4.6 on Linux.
