How to drop keys from internal sks keyserver

Question

How do I drop keys from an internal SKS keyserver.

SKS fingerprints are in SHA1, but sks drop command is looking for an md5, how do I properly get the MD5 fingerprint from a key on an sks keyserver.

This command gives the SHA1 Fingerprint

gpg --fingerprint username

sks drop $(sha1_fingerprint)
hash should be exactly 32 characters long

Answer 1

that should be :

1. Export pub key to a file
2. md5sum <key_file>

Answer 2

md5sum not working any more, because of now keyHash is MD5 hash of sorted key, for me has worked:

• get hash in browser, by adding &hash=on to sks url
• sks drop ${hash_from_web}
