[tor-talk] onion id calculation

[grarpamp <grarpamp@xxxxxxxxx>]

rend-spec...
"permanent-id" is the permanent identifier of the hidden service,
consisting of 80 bits. It can be calculated by computing the hash value
of the public hidden service key and truncating after the first 80 bits:
 permanent-id = H(public-key)[:10]

https://trac.torproject.org/projects/tor/wiki/doc/HiddenServiceNames
To run a hidden service, Tor generates an  RSA-1024 keypair. The .onion
name is computed as follows: first the  SHA1 hash of the  DER-encoded
ASN.1 public key is calculated. Afterwards the first half of the hash is
encoded to  Base32 and the suffix ".onion" is added.

What am I doing wrong besides being sleepy?
Here also, using half(20 chars) of the hash would yield a 32 char onion id.
