Rsa Keys Cannot Be Generated As System Clock Is Invalid
If you do not generate the key pair before the certificate server is created on the router, a general-purpose key pair is automatically generated during the configuration of the certificate server. The CA certificate and CA key can be backed up automatically one time after they are generated by the certificate server. Jan 14, 2009 First, we need to generate an RSA public/private key pair on both of the endpoint routers. R1(config)# crypto key generate rsa general-keys label R1 The name for the keys will be: R1 Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. % Rsa keys can't be generated by the startup configuration. If we tftp the config without the following commands and then put it in manually after the tftp load it works fine: crypto key gen rsa gen mod 1024. I did the following on a Cisco 3745 router running 12.4 in the lab: 1. Copied the config from router to tftp server.
'Fingerprint cannot be generated' and other SSH key problems
My problem is that I can't add an SSH key or Deploy key without Fingerprint has already been taken
and Fingerprint cannot be generated
errors.
The full story is a little complex, but something like this: I did once successfully add an SSH key to my new account, then couldn't successfully add a Deploy key. After many struggles, I deleted my SSH key in an attempt to 'start clean.' At that point, I was unable to even add a newly-generated SSH key. After generating a few new keys and failing to get those to work, I deleted my GitLab.com account altogether and remade it.
Rsa Keys Cannot Be Generated As System Clock Is Invalid File
After remaking my account, I'm still unable to add newly-generated SSH or Deploy keys without Fingerprint has already been taken
and Fingerprint cannot be generated
errors.
I'm generating my SSH keys on a Debian system withssh-keygen -t rsa -C '[email protected]'
and carefully making sure that there are no newlines, extra spaces or missing characters in what I'm pasting into the web UI.
The SSH keys I'm pasting start with ssh-rsa
and end with the email address associated with my GitLab.com account.
This is all regarding my bland328
account and my single private project, which is currently empty.
I've searched for help, and do find references to people experiencing similar problems and fixing it by manually deleting orphaned key data from the database, which I obviously can't do as a user of Gitlab.com.
Is there something I'm missing with regard to key management? Or some good way to properly reset things or otherwise work around this?

5.3.1 Creating SSL and RSA Certificates and Keys using MySQL
MySQL provides these ways to create the SSL certificate and key files and RSA key-pair files required to support encrypted connections using SSL and secure password exchange using RSA over unencrypted connections, if those files are missing:
The server can autogenerate these files at startup, for MySQL distributions compiled using OpenSSL.
Users can invoke the mysql_ssl_rsa_setup utility manually.
For some distribution types, such as RPM packages, mysql_ssl_rsa_setup invocation occurs during data directory initialization. In this case, the MySQL distribution need not have been compiled using OpenSSL as long as the openssl command is available.
Server autogeneration and mysql_ssl_rsa_setup help lower the barrier to using SSL by making it easier to generate the required files. However, certificates generated by these methods are self-signed, which may not be very secure. After you gain experience using such files, consider obtaining certificate/key material from a registered certificate authority.
Rsa Keys Cannot Be Generated As System Clock Is Invalid Error
For MySQL distributions compiled using OpenSSL, the MySQL server has the capability of automatically generating missing SSL and RSA files at startup. The auto_generate_certs
and sha256_password_auto_generate_rsa_keys
system variables control automatic generation of these files. These variables are enabled by default. They can be enabled at startup and inspected but not set at runtime.
At startup, the server automatically generates server-side and client-side SSL certificate and key files in the data directory if the auto_generate_certs
system variable is enabled, no SSL options other than --ssl
are specified, and the server-side SSL files are missing from the data directory. These files enable encrypted client connections using SSL; see Section 5.1, “Configuring MySQL to Use Encrypted Connections”.
The server checks the data directory for SSL files with the following names:
If any of those files are present, the server creates no SSL files. Otherwise, it creates them, plus some additional files: Adobe acrobat x key generator.
If the server autogenerates SSL files, it uses the names of the
ca.pem
,server-cert.pem
, andserver-key.pem
files to set the corresponding system variables (ssl_ca
,ssl_cert
,ssl_key
).
At startup, the server automatically generates RSA private/public key-pair files in the data directory if all of these conditions are true: The sha256_password_auto_generate_rsa_keys
system variable is enabled; no RSA options are specified; the RSA files are missing from the data directory. These key-pair files enable secure password exchange using RSA over unencrypted connections for accounts authenticated by the sha256_password
plugin; see Section 6.1.5, “SHA-256 Pluggable Authentication”.
The server checks the data directory for RSA files with the following names:
If any of these files are present, the server creates no RSA files. Otherwise, it creates them.
If the server autogenerates the RSA files, it uses their names to set the corresponding system variables (
sha256_password_private_key_path
,sha256_password_public_key_path
).
Manual SSL and RSA File Generation Using mysql_ssl_rsa_setup
Rsa Keys Cannot Be Generated As System Clock Is Invalid Code
MySQL distributions include a mysql_ssl_rsa_setup utility that can be invoked manually to generate SSL and RSA files. This utility is included with all MySQL distributions, but it does require that the openssl command be available. For usage instructions, see mysql_ssl_rsa_setup — Create SSL/RSA Files.
Rsa Keys Cannot Be Generated As System Clock Is Invalid Number
SSL and RSA files created automatically by the server or by invoking mysql_ssl_rsa_setup have these characteristics:
SSL and RSA keys are have a size of 2048 bits.
The SSL CA certificate is self signed.
The SSL server and client certificates are signed with the CA certificate and key, using the
sha256WithRSAEncryption
signature algorithm.SSL certificates use these Common Name (CN) values, with the appropriate certificate type (CA, Server, Client):
The
suffix
value is based on the MySQL version number. For files generated by mysql_ssl_rsa_setup, the suffix can be specified explicitly using the--suffix
option.For files generated by the server, if the resulting CN values exceed 64 characters, the
_
portion of the name is omitted.suffix
SSL files have blank values for Country (C), State or Province (ST), Organization (O), Organization Unit Name (OU) and email address.
SSL files created by the server or by mysql_ssl_rsa_setup are valid for ten years from the time of generation.
RSA files do not expire.
SSL files have different serial numbers for each certificate/key pair (1 for CA, 2 for Server, 3 for Client).
Files created automatically by the server are owned by the account that runs the server. Files created using mysql_ssl_rsa_setup are owned by the user who invoked that program. This can be changed on systems that support the
chown()
system call if the program is invoked byroot
and the--uid
option is given to specify the user who should own the files.On Unix and Unix-like systems, the file access mode is 644 for certificate files (that is, world readable) and 600 for key files (that is, accessible only by the account that runs the server).
To see the contents of an SSL certificate (for example, to check the range of dates over which it is valid), invoke openssl directly:
It is also possible to check SSL certificate expiration information using this SQL statement:
