# openssl genrsa
|
|
|
|
> OpenSSL command to generate RSA private keys.
|
|
> More information: <https://docs.openssl.org/master/man1/openssl-genrsa/>.
|
|
|
|
- Generate an RSA private key of 2048 bits to `stdout`:
|
|
|
|
`openssl genrsa`
|
|
|
|
- Save an RSA private key of an arbitrary number of bits to the output file:
|
|
|
|
`openssl genrsa -out {{output_file.key}} {{1234}}`
|
|
|
|
- Generate an RSA private key and encrypt it with AES256 (you will be prompted for a passphrase):
|
|
|
|
`openssl genrsa {{-aes256}}`
