This document attempts to present a much more detailed, thorough, and easily-understood form of the key formats used by OpenSSH. The extent of those formats' canonical documentation is https://github.com/openssh/openssh-portable/blob/master/PROTOCOL.key[the OpenSSH source tree's `PROTOCOL.key`^], which is a little lacking.

==== Private Keys
|
||||||
|
|
||||||
|
Private key structures have been retooled in the "v1" format. In recent OpenSSH versions, all new keys use the v1 format. They no longer are in straight PEM-compatible format.
|
||||||
|
|
||||||
|
Refer to https://github.com/openssh/openssh-portable/blob/master/PROTOCOL.key[`PROTOCOL.key`^] for a (very) general description, or each key's specific breakdown for more detailed information.
|
||||||
|
|
||||||
|
The v1 format offers several benefits over the legacy format, including:
|
||||||
|
|
||||||
|
* customizable key derivation and encryption ciphers for encrypted private keys
|
||||||
|
* embedded comments
|
||||||
|
* embedded public key (no need to derive from the private key)
|
||||||
|
* "checksumming" to confirm proper decryption for encrypted keys
|
||||||
|
|
||||||
==== Public Keys
|
==== Public Keys
|
||||||
|
|

All public keys in v1 continue to use the same packed binary format as <<public_keys, the legacy format>>.

=== ED25519
|
||||||
|
|
||||||
|
ED25519footnote:[https://datatracker.ietf.org/doc/html/rfc8709] is a relatively somewhat new OpenSSH key algorithm. It has numerous benefits over e.g. RSA, including:
|
||||||
|
|
||||||
|
* fixed key sizes, so fixed pubkey sizes
|
||||||
|
** and significantly shorter pubkeys, yet-
|
||||||
|
* strength comparable to RSA4096, but-
|
||||||
|
** much faster
|
||||||
|
* public domain and https://ed25519.cr.yp.to/[developed by independent researchers^]; not tied to specific corporation (i.e. nothing like https://en.wikipedia.org/wiki/RSA_Security[RSA^])
|
||||||
|
|
||||||
|
I recommend it over all other key types for new SSH keys as long as it's supported by clients/servers.

Currently, the only supported KDF is *bcrypt_pbkdf* (`bcrypt`).
|
||||||

|

See the following for more details:

[TIP]
|
||||||
|
====
|
||||||
|
You can get a list of supported ciphers (*1.0.0*) via `ssh -Q cipher` on most systems.
|
||||||
|
Note that *1.0.0* has nothing to do with SSH connections themselves; it's *only* for the encryption of *4.0.1*.
|
||||||
|
|
||||||
|
This is likely going to be:
|
||||||
|
|
||||||
|
* `3des-cbc`
|
||||||
|
* `aes128-cbc`
|
||||||
|
* `aes192-cbc`
|
||||||
|
* `aes256-cbc`
|
||||||
|
* `rijndael-cbc@lysator.liu.se` _(may not be present on all systems)_
|
||||||
|
* `aes128-ctr`
|
||||||
|
* `aes192-ctr`
|
||||||
|
* `aes256-ctr`
|
||||||
|
* `aes128-gcm@openssh.com`
|
||||||
|
* `aes256-gcm@openssh.com`
|
||||||
|
* `chacha20-poly1305@openssh.com`
|
||||||
|
|
||||||
|
The author recommends using `aes256-ctr`. It is currently the upstream default.

Since plaintext/unencrypted keys do not have a cipher or KDF (as there's no encryption key or algorithm used), they use the string "none" to identify these (and entirely leave out the KDF options).

Currently, the only supported KDF is *bcrypt_pbkdf* (`bcrypt`).
|
||||||
|
|
||||||

See the following for more details:

[TIP]
|
||||||
|
====
|
||||||
|
You can get a list of supported ciphers (*1.0.0*) via `ssh -Q cipher` on most systems.
|
||||||
|
Note that *1.0.0* has nothing to do with SSH connections themselves; it's *only* for the encryption of *4.0.1*.
|
||||||
|
|
||||||
|
This is likely going to be:
|
||||||
|
|
||||||
|
* `3des-cbc`
|
||||||
|
* `aes128-cbc`
|
||||||
|
* `aes192-cbc`
|
||||||
|
* `aes256-cbc`
|
||||||
|
* `rijndael-cbc@lysator.liu.se` _(may not be present on all systems)_
|
||||||
|
* `aes128-ctr`
|
||||||
|
* `aes192-ctr`
|
||||||
|
* `aes256-ctr`
|
||||||
|
* `aes128-gcm@openssh.com`
|
||||||
|
* `aes256-gcm@openssh.com`
|
||||||
|
* `chacha20-poly1305@openssh.com`
|
||||||
|
|
||||||
|
The author recommends using `aes256-ctr`. It is currently the upstream default.

*Chunk 4.0:* This is technically currently unused; upstream hardcodes to 1 (left zero-padded 0x01).

|
*Chunk 4.0.1.0:* When decrypted, this is equivalent to the <<struct_rsa_plain,plaintext>> *4.0.1.0* to *4.0.1.6*. It uses a padded size appropriate to the encryption cipher used.

The decrypted *4.0.1.0* should match the <<struct_rsa_plain, plaintext key's structure>> for *4.0.1.0* through *4.0.1.10*. The padding length WILL change, however, between the two unless using a cipher with an 8-byte block size.

When *4.0.1.0* is decrypted, it yields:

[TIP]
|
||||||
|
====
|
||||||
|
Since plaintext/unencrypted keys do not have a cipher or KDF (as there's no encryption key or algorithm used), they use the string "none" to identify these (and entirely leave out the KDF options).

[NOTE]
|
||||||
|
====
|
||||||
|
*Chunk 3.0.0 to 3.0.1:* These blocks are not present in unencrypted keys (see the <<struct_rsa_crypt, encrypted key structure>> for what these look like). *3.0* reflects this, as it's always going to be `00000000` (0).
|
||||||
|
|
||||||
|
*Chunk 4.0:* This is technically currently unused; upstream hardcodes to 1 (left zero-padded 0x01).
|
||||||
|
|
||||||
|
*Chunk 4.0.0.1.0, 4.0.0.2.0, 4.0.1.3.0, 4.0.1.4.0:* Note that the ordering of `e`/`n` in *4.0.0* is changed to `n`/`e` in *4.0.1*.
|
||||||
|
|
||||||
|
*Chunk 4.0.1.10:* The padding used aligns the private key (*4.0.1.0* to *4.0.1.9.0*) to the cipher blocksize. For plaintext keys, a blocksize of 8 is used.
