Hi Peter,
Thanks for the reply.
I did browse the man pages quite a bit (I am a bit afraid I browsed too
much and touched stuff I should leave well alone :))
I did set my key preferences a few months ago and made sure the key had
them as well. Here is the output of showperf:
Cipher: AES256, AES192, AES, CAST5, 3DES
Digest: SHA512, SHA384, SHA256, SHA224, SHA1
Compression: ZLIB, BZIP2, ZIP, Uncompressed
Features: MDC, Keyserver no-modify
Also here is all the stuff I have in my gpg.conf:
```
personal-cipher-preferences AES256 TWOFISH CAMELLIA256 AES192
CAMELLIA192 AES CAST5 CAMELLIA128 BLOWFISH IDEA 3DES
personal-digest-preferences SHA512 SHA384 SHA256 SHA224 AES256 AES192
AES CAST5 ZLIB BZIP2 ZIP Uncompressed
s2k-digest-algo SHA512
keyserver hkps://hkps.pool.sks-keyservers.net
keyserver-options
ca-cert-file=/home/martin/.gnupg/sks-keyservers.netCA.pem
keyserver-options no-honor-keyserver-url
keyid-format 0xlong
with-fingerprint
cert-digest-algo SHA512
default-preference-list SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES
CAST5 ZLIB BZIP2 ZIP Uncompressed
use-agent
```
Let me know if you need more info.
Regards,
Martin
