-## Similar Projects ##
-
-The monkeysphere isn't the only project intending to implement a PKI
-for OpenSSH. We provide links to these other projects because they're
-interesting, though we have concerns with their approaches.
-
-All of the other projects we've found so far require a patched version
-of OpenSSH, which makes adoption more difficult. Most people don't
-build their own software, and simply overlaying a patched binary is
-associated with significant maintenance (and therefore security)
-problems. A PKI becomes more useful the more people participate in
-it, so widespread adoption is important.

-### `openssh-gpg` ###
-
-[openssh-gpg](http://www.red-bean.com/~nemo/openssh-gpg/) is a patch
-against OpenSSH to support OpenPGP certificates. According to its
-documentation, it is intended to support [`pgp-sign-rsa` and
-`pgp-sign-dss` public key algorithms, as specified by the
-IETF](http://tools.ietf.org/html/rfc4253#section-6.6).
-
-Some concerns with `openssh-gpg`:
-
- * This patch is significantly old; it doesn't appear to have been
- maintained beyond OpenSSH 3.6p1. As of this writing, OpenSSH is on
- version 5.1p1.
-
- * It requires patching OpenSSH.
-
-### Perspectives OpenSSH client ###
-
-[The Perspectives project](http://www.cs.cmu.edu/~perspectives/) at
-CMU has released an [openssh client that uses network
-notaries](http://www.cs.cmu.edu/~perspectives/openssh.html) to bolster
-your confidence in new keys. This offers a defense against a narrow
-MITM attack (e.g. by someone who controls your local gateway) by
-simply verifying that other machines from around the network see the
-same keys for the remote host that you're seeing.
-
-This is quite useful, but doesn't take the system as far as it could
-go, and doesn't tie into the existing web of trust.
-
-Some concerns with the Perspectives OpenSSH client:
-
- * This client won't help if you are connecting to machines behind
- firewalls, on NAT'ed LANs, with source IP filtering, or otherwise
- in a restricted network state.
-
- * There is still a question of why you should trust these particular
- notaries during your verification. Who are the notaries? How
- could they be compromised?
-
- * It requires patching OpenSSH
-
-### OpenSSH with X.509v3 certificates ###
-
-Roumen Petrov [maintains a patch to OpenSSH that works with the X.509
-PKI model](http://www.roumenpetrov.info/openssh/). This is the
-certificate hierarchy commonly used by TLS (and SSL before that).
-
-Some concerns about OpenSSH with X.509v3:
-
- * the X.509 certificate specification itself [encourages corporate
- consolidation and centralized global "trust" because of its
- single-issuer architectural
- limitation](http://lair.fifthhorseman.net/~dkg/tls-centralization/).
- This results in an expensive and cumbersome system for smaller
- players, and it also doesn't correspond to the true distributed
- nature of human-to-human trust. Furthermore, centralized global
- "trusted authorities" create a tempting target for attack, and a
- single-point-of-failure if an attack is successful.
-
- Depending on how you declare your trust relationships, OpenPGP is
- capable of providing the same hierarchical structure as X.509, but
- it is not limited to it. The Web of Trust model is more flexible
- and more adaptable than X.509.
