openssl genrsa -out key.pem: openssl rsa -in key.pem -out key.pub -pubout # Encrypt and Decrypt a file (using public key to encrypt) echo--pass-- > pass.txt: openssl rsautl -in pass.txt -out pass.enc -pubin -inkey key.pub -encrypt: openssl rsautl -in pass.enc -out pass.dec -inkey key.pem -decrypt: cat pass.dec # Compress, Encrypt, Decyrpt, Uncompress a file (using password in pass.txt) echo. openssl genrsa -out key.pem 2048. Der Schlüssel mit 2048 Bit Schlüsselstärke ist nun in der Datei key.pem gespeichert, welche Sie mit einem einfachen Texteditor lesen können. 1.2 ECC-Schlüssel . Private Schlüssel auf Basis von elliptischen Kurven haben den Vorteil, dass sie mit wesentlich kürzeren Schlüssellängen eine gleichwertige Sicherheit bieten. Der Nachteil ist allerdings die. openssl genrsa -des3 -out key.pem 2048 . The file, key.pem, generated in the examples above actually contains both a private and public key. To view the public key you can use the following command: openssl rsa -in key.pem -pubout. Generate a CSR. If you already have a key, the command below can be used to generates a CSR and save it to a file called req.pem. This is an interactive command. We encrypt the large file with the small password file as password. Then we send the encrypted file and the encrypted key to the other party and then can decrypt the key with their public key, the use that key to decrypt the large file. The following commands are relevant when you work with RSA keys: openssl genrsa: Generates an RSA private keys OpenSSL is able to read passwords from a variety of other sources, so if you remove the ~/.pas file and supply the password from a more secure source, the use of a single RSA key for both SSH network sessions and OpenSSL flat file encryption becomes more of an option

If you have a PFX file that contains a private key with a password, you can use OpenSSL to extract the private key without a password into a separate file, or create a new PFX file without a password. Get the Private Key from the key-pair #openssl rsa -in sample.key -out sample_private.key to the CA, they will return a signed certificate which you can combine with your private key into a pfx. OpenSSL useful commands. Creating a key for SSL-certificate. If you do not specify -des3, it will be without a password: # Openssl genrsa -des3 -out example.com.key 2048 CSR-request: # Openssl req -new -key example.com.key -out example.com.csr Remove password from the key: # Openssl rsa -in example.com.key -out example.com-nopass.key -passin stdi openssl genrsa -out www.domain.de.key 2048. Wichtig: Machen Sie ein Backup des privaten Schlüssels (am besten an einem sicheren Ort, z.B. auf einem USB-Stick), denn wenn er verloren geht, ist Ihr SSL-Zertifikat wertlos! Danach erzeugen Sie den CSR: openssl req -new -key www.domain.de.key -out www.domain.de.csr. Die folgenden Informationen werden nun abgefragt: Country Name (2 letter code): DE.
