# Generating RSA keys
|
||
|
|
|
||
|
|
Using `openssl`
|
||
|
|
|
||
|
|
## PEM
|
||
|
|
`openssl genrsa -out private_rsa_key.pem 2048`
|
||
|
|
|
||
|
|
Getting public key:
|
||
|
|
`openssl rsa -in private_rsa_key.pem -outform PEM -pubout -out public_rsa_key.pem`
|
||
|
|
|
||
|
|
## DER
|
||
|
|
Same as PEM but replace `PEM` by `DER`.
|
||
|
|
`openssl rsa -in private_rsa_key.pem -outform DER -pubout -out public_rsa_key.der`
|
||
|
|
|
||
|
|
## Converting private PEM to DER
|
||
|
|
`openssl rsa -in private_rsa_key.pem -outform DER -out private_rsa_key.der`
|
||
|
|
|
||
|
|
## Converting private DER to PEM
|
||
|
|
`openssl rsa -in private_rsa_key.der -inform DER -outform PEM -out private_rsa_key.pem`
|
