PGP encryption uses a serial combination of hashing, data compression, symmetric-key cryptography, and finally public-key cryptography; each step uses one of several supported algorithms.Each public key is bound to a username or an e-mail address. The first version of this system was generally known as a web of trust to contrast with the X.509 system, which uses a hierarchical approach based.

To remove the pass phrase on an RSA private key : openssl rsa -in key .pem -out keyout.pem To encrypt a private key using triple DES: openssl rsa -in key .pem -des3 -out keyout.pem. If, for any reason, you need to generate a certificate signing request for an existing private key, use the following OpenSSL command: openssl req -out CSR.csr -key. To convert a key into the .ppk format using PuTTYgen: Start PuTTYgen, and in the Conversions menu, click Import key . In the Load private key window, browse to your SSH private key , select it, and then click Open . Enter the passphrase associated with the private key . Note that the key fingerprint confirms the number of bits is 4096. Therefore the first step, once having decided on the algorithm, is to generate the private key. In these examples the private key is referred to as privkey.pem. For example, to create an RSA private key using default parameters, issue the following command: ~]$ openssl genpkey -algorithm RSA -out privkey.pem.. The Commands to Run Generate a 2048 bit RSA Key You can generate a public and private RSA key pair like this: openssl genrsa -des3 -out private.pem 2048 That generates a 2048-bit RSA key pair, encrypts them with a password you provide and writes them to a file. You need to next extract the public key file.

It leads us to think that we will generate a 256 bit random key and OpenSSL will use it to perform a symmetric encryption. However, we are using a secret password (length is much shorter than the RSA key size) to derive a key. OpenSSL uses this password to derive a random key and IV. This key will be used for symmetric encryption.
