 ## 0.0.13-beta to 0.0.14-beta
 
+* Due to changes to supported algorithms in newer versions of openssl, the default list of supported algorithms for the ssh login server has changed. There are both removed ciphers as well as optional new kex algorithms available now. ***NOTE:*** Changes to supported algorithms are only needed to support keys generated with new versions of openssl, if you already have a ssl key in use you should not have to make any changes to your config.
+  * Removed ciphers: 'blowfish-cbc', 'arcfour256', 'arcfour128', and 'cast128-cbc'
+  * Added kex: 'curve25519-sha256', 'curve25519-sha256@libssh.org', 'curve25519-sha256', 'curve25519-sha256@libssh.org', 'ecdh-sha2-nistp256', 'ecdh-sha2-nistp384', 'ecdh-sha2-nistp521'
+
 ## 0.0.12-beta to 0.0.13-beta
 * To enable the new Waiting for Caller (WFC) support, please see [WFC](docs/modding/wfc.md).
 * :exclamation: The SSH server's `ssh2` module has gone through a major upgrade. Existing users will need to comment out two SSH KEX algorithms from their `config.hjson` if present else clients such as NetRunner will not be able to connect over SSH. Comment out `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1`

 The ENiGMA½ SSH *login server* allows secure user logins over SSH (ssh://).

 ## Generate a SSH Private Key
+
 To utilize the SSH server, an SSH Private Key (PK) will need generated. OpenSSH or (with some versions) OpenSSL can be used for this task:
 
-### OpenSSH
+### OpenSSH (Preferred)
 
-```bash
-ssh-keygen -m PEM -h -f config/ssh_private_key.pem
+#### OpenSSH Install - Linux / Mac
+
+If it is not already available, install OpenSSH using the package manager of your choice (should be pre-installed on most distributions.)
+
+#### Running OpenSSH - Linux / Mac
+
+From the root directory of the Enigma BBS, run the following:
+
+```shell
+mkdir -p config/security
+ssh-keygen -t rsa -m PEM -h -f config/security/ssh_private_key.pem
 ```
 
+#### Windows Install - OpenSSH
+
+OpenSSH may already be installed, try running `ssh-keygen.exe`. If not, see this page: [Install OpenSSH for Windows](https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui)
+
+#### Running OpenSSH - Windows
+
+After installation, go to the root directory of your enigma project and run:
+
+```powershell
+mkdir .\config\security -ErrorAction SilentlyContinue
+ssh-keygen.exe -t rsa -m PEM -h -f .\config\security\ssh_private_key.pem
+```
+
+#### ssh-keygen options
+
 Option descriptions:
 
 | Option | Description |
 |------|-------------|
+| `-t rsa` | Use the RSA algorithm needed for the `ssh2` library |
 | `-m PEM` | Set the output format to `PEM`, compatible with the `ssh2` library |
 | `-h` | Generate a host key |
 | `-f config/ssh_private_key.pem` | Filename for the private key. Used in the `privateKeyPem` option in the configuration |
 
 When you execute the `ssh-keygen` command it will ask for a passphrase (and a confirmation.) This should then be used as the value for `privateKeyPass` in the configuration.
 
-
 ### OpenSSL
 
-If you do not have OpenSSH installed or if you have trouble with the above OpenSSH commands, using some versions for OpenSSL (before version 3) the following commands may work as well:
+#### Open SSL Install - Linux / Mac
 
+If not already installed, install via the `openssl` package on most package managers.
 
-```bash
-openssl genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -pkeyopt rsa_keygen_pubexp:65537 | openssl rsa -out ./config/ssh_private_key.pem -aes128
+#### Open SSL Install - Windows
+
+```powershell
+winget install -e --id ShiningLight.OpenSSL
 ```
 
-Or for even older OpenSSL versions:
+#### Running OpenSSL
 
-```bash
+*Note:* Using `ssh-keygen` from OpenSSL is recommended where possible. If you have trouble with the above OpenSSH commands, using some versions for OpenSSL (before version 3) the following commands may work as well:
+
+#### Running OpenSSL - Linux / Mac
+
+Run the following from the root directory of Enigma
+
+```shell
+mkdir -p config/security
+openssl genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -pkeyopt rsa_keygen_pubexp:65537 | openssl rsa -out ./config/security/ssh_private_key.pem -aes128
+```
+
+#### Running OpenSSL - Windows
+
+Run the following from the root directory of Enigma (note: you may need to specify the full path to openssl.exe if it isn't in your system path, on my system it was `C:\Program Files\OpenSSL-Win64\bin\openssl.exe`):
+
+```powershell
+mkdir .\config\security -ErrorAction SilentlyContinue
+openssl.exe genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -pkeyopt rsa_keygen_pubexp:65537 | openssl.exe rsa -out ./config/security/ssh_private_key.pem -aes128
+```
+
+#### Running Older OpenSSL
+
+For older OpenSSL versions, the following command has been known to work:
+
+```shell
 openssl genrsa -aes128 -out ./config/ssh_private_key.pem 2048
 ```
 
-Note that you may need `-3des` for very old implementations or SSH clients!

 ## Prompt
 
-The keyboard interactive prompt can be customized using a `SSHPMPT.ASC` art file. See [art](../../art/general.md) for more information on configuring. This prompt includes a `newUserNames` variable to show the list of allowed new user names (see `firstMenuNewUser` above.) See [mci](../../art/mci.md) for information about formatting this string. Note: Regardless of the content of the `SSHPMPT.ASC` file, the prompt is surrounded by "Access denied", a newline, the prompt, another newline, and then the string "\[username]'s password: ". This normally occurs after the first password prompt (no art is shown before the first password attempt is made.)

+Stuck with errors trying to get your SSH setup configured? See below for some common problems. Or as always, reach out to us by creating an [Issue](https://github.com/NuSkooler/enigma-bbs/issues) or start a [Discussion](https://github.com/NuSkooler/enigma-bbs/discussions)
+
+## No Such File or Directory
+
+***Symptom:***
+BBS not starting with an error similar to the following:
+
+```shell
+Error initializing: Error: ENOENT: no such file or directory, open '<path>/config/security/ssh_private_key.pem'
+```
+
+***Solution:***
+Several things can cause this:
+
+1. `ssh_private_key.pem` was installed to the wrong location. Make sure that it is in the `config/security` directory and has the name matching the error message. You can also change your `config.hjson` if you prefer to point to the location of the key file.
+2. `ssh_private_key.pem` has the wrong file permissions. Verify that the file will be readable by the user that the BBS is running as. Because it is a cryptographic key however, we do recommend that access is restricted only to that user.
+
+## Error With Netrunner
+
+***Symptom:***
+Some ssh clients connect, but Netrunner (and other older clients) get a connection failed message and the following is in the log:
+
+```shell
+"level":40,"error":"Handshake failed","code":2,"msg":"SSH connection error"
+```
+
+***Solution:***
+
+The key was most likely not generated with the `-t rsa` option, and is using a newer algorithm that is not supported by Netrunner and similar clients. Regenerate the certificate with the `-t rsa` option.
+
+***Symptom:***
+Some ssh clients connect, but Netrunner (and other older clients) get a connection failed message and the following is in the log:
+
+```shell
+"level":40,"error":"Group exchange not implemented for server","msg":"SSH connection error"
+```
+
+***Solution:***
+
+Remove the following encryption protocols from your `config.hjson`: `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1`
