Ssh-keygen -t rsa -b 2048 You can use “dsa” instead of the “rsa” after the -t to generate a DSA key. The number after the -b specifies the key length in bits. After executing the command it may take some time to generate the keys (as the program waits for enough entropy to be gathered to generate random numbers). 2019-9-6 If you interact regularly with SSH commands and remote hosts, you may find that using a key pair instead of passwords can be convenient. Instead of the remote system prompting for a password with each connection, authentication can be automatically negotiated using a public and private key pair. So speaking only of security (not speed!), why should one not prefer RSA 4096 over Ed25519? If Ed25519 only provides 3000 bit key strength, RSA with 4096 bit should be much more secure?

- This module allows one to (re)generate OpenSSH private and public keys. It uses ssh-keygen to generate keys. One can generate

,rsa1

private keys.
The below requirements are needed on the host that executes this module.
- ssh-keygen
Parameter | Choices/Defaults | Comments |
---|---|---|
attributes string | The attributes the resulting file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr. The = operator is assumed as default, otherwise + or - operators need to be included in the string. | |
comment added in 2.9 | Provides a new comment to the public key. When checking if the key is in the correct state this will be ignored. | |
force boolean |
| Should the key be regenerated even if it already exists |
group string | Name of the group that should own the file/directory, as would be fed to chown. | |
mode string | The permissions the resulting file or directory should have. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777 ) or quote it (like '644' or '1777' ) so Ansible receives a string and can do its own conversion from string into number.Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r ).As of Ansible 2.6, the mode may also be the special string preserve .When set to preserve the file will be given the same permissions as the source file. | |
owner string | Name of the user that should own the file/directory, as would be fed to chown. | |
path path / required | Name of the files containing the public and private key. The file containing the public key will have the extension .pub . | |
selevel string | Default: | The level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range .When set to _default , it will use the level portion of the policy if available. |
serole string | When set to _default , it will use the role portion of the policy if available. | |
setype string | When set to _default , it will use the type portion of the policy if available. | |
seuser string | By default it uses the system policy, where applicable.When set to _default , it will use the user portion of the policy if available. | |
size integer | Specifies the number of bits in the private key to create. For RSA keys, the minimum size is 1024 bits and the default is 4096 bits. Generally, 2048 bits is considered sufficient. DSA keys must be exactly 1024 bits as specified by FIPS 186-2. For ECDSA keys, size determines the key length by selecting from one of three elliptic curve sizes: 256, 384 or 521 bits. Attempting to use bit lengths other than these three values for ECDSA keys will cause this module to fail. Ed25519 keys have a fixed length and the size will be ignored. | |
state string |
| Whether the private and public keys should exist or not, taking action if the state is different from what is stated. |
type string |
| The algorithm used to generate the SSH private key. rsa1 is for protocol version 1. rsa1 is deprecated and may not be supported by every version of ssh-keygen. |
unsafe_writes boolean |
| Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file. By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes). IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption. |
