difference between openssl and ssh rsa-public-keys

[Gerd Schering]

Hello,

I generated an rsa key with ssh-keygen:

-----BEGIN RSA PRIVATE KEY-----
MIICWwIBAAKBgQC/mID2ohE8oahTW2/v0uXOKe/98Lxywo8p0D56prYHlMIUoTMk

-----END RSA PRIVATE KEY-----

Then I extracted the public key,
1. with openssl:

-----BEGIN PUBLIC KEY-----
MIGdMA0GCSqGSIb3DQEBAQUAA4GLADCBhwKBgQC/mID2ohE8oahTW2/v0uXOKe/9
8Lxywo8p0D56prYHlMIUoTMkouoY+DfbF65a1gNQaLCp2izqSPQZvHk9RqESpGkT

raEdYAWxZUUn3iTv1wIBIw==
-----END PUBLIC KEY-----

2. with ssh-keygen:

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAv5iA9qIRPKGoU1tv79Llzinv/fC8csKPKdA+e \
qa2B5TCFKEzJKLqGPg32xeuWtYDUGiwqdos6kj0Gbx5PUahEqRpE3X/L6Hvbjjc/dNsWfX+Xy \
VYItgEkLyqRM5WTllbjz11qk3tXqkC0N/cAGl/06gOoa2hHWAFsWVFJ94k79c=
(there are no newlines)

They look different and the ssh key is not in PEM format.
But besides that by which means is this difference produced?
Or s it only the lack of header-, footer-, newlines and the "ssh-rsa" which produces a different base64 encoding?

B.t.w In PEM format, are the newlines part of the base64-encoded data, or get the data encoded first?

Thanks,
Gerd
