Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen.[2][3]

Using SSH User Certificates with PIV keys. Generate an 'ssh user CA' key and trust it for this account on this host. And extension (.so for Linux,.dylib for Mac OS X) for libykcs11. Beware that ssh-add -D doesn’t seem to clear PKCS#11 libraries, only keys. Applied PKCS #11¶. PKCS #11 is the name given to a standard defining an API for cryptographic hardware. While it was developed by RSA, as part of a suite of standards, the standard is not exclusive to RSA ciphers and is meant to cover a wide range of cryptographic possibilities. Apr 23, 2014  PKCS #11 Cryptographic Token Interface Current Mechanisms Specification Version 2.40. PKCS #11 Cryptographic Token Interface Current Mechanisms Specification Version 2.40. Unlike the CKMRSAPKCSKEYPAIRGEN mechanism, this mechanism is guaranteed to generate p. Nov 16, 2018  The SmartCard-HSM is a lightweight hardware security module in a smart card form factor. The Nitrokey HSM is a lightweight hardware security module in a USB key form factor containing the SmartCard-HSM.Both are 100% compatible and provide a remote-manageable secure key store for RSA and ECC keys. The SmartCard-HSM is available as USB key, ID-1 card with contact/contactless.

Generate an RSA keypair with a 2048 bit private key[edit]

Execute command: 'openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048'[4] (previously “openssl genrsa -out private_key.pem 2048”)

e.g.


Make sure to prevent other users from reading your key by executing chmod go-r private_key.pem afterward.

Extracting the public key from an RSA keypair[edit]

Execute command: 'openssl rsa -pubout -in private_key.pem -out public_key.pem'

e.g. Windows 8.1 pro n product key generator.

A new file is created, public_key.pem, with the public key. Freeware download: mpc star tiger player for mac.

It is relatively easy to do some cryptographic calculations to calculate the public key from the prime1 and prime2 values in the public key file.However, OpenSSL has already pre-calculated the public key and stored it in the private key file.So this command doesn't actually do any cryptographic calculation -- it merely copies the public key bytes out of the file and writes the Base64 PEM encoded version of those bytes into the output public key file.[5]

Viewing the key elements[edit]

Execute command: 'openssl rsa -text -in private_key.pem'

All parts of private_key.pem are printed to the screen. This includes the modulus (also referred to as public key and n), public exponent (also referred to as e and exponent; default value is 0x010001), private exponent, and primes used to create keys (prime1, also called p, and prime2, also called q), a few other variables used to perform RSA operations faster, and the Base64 PEM encoded version of all that data.[6](The Base64 PEM encoded version of all that data is identical to the private_key.pem file).

Password-less login[edit]

Often a person will set up an automated backup process that periodically backs up all the content on one 'working' computer onto some other 'backup' computer.

Because that person wants this process to run every night, even if no human is anywhere near either one of these computers, using a 'password-protected' private key won't work -- that person wants the backup to proceed right away, not wait until some human walks by and types in the password to unlock the private key.Many of these people generate 'a private key with no password'.[7]Some of these people, instead, generate a private key with a password,and then somehow type in that password to 'unlock' the private key every time the server reboots so that automated toolscan make use of the password-protected keys.[8][3]
