Generate a RSA PEM key pair from pure JS
Generate a key pair with a third-party tool of your choice. Save the public key to a local file. For example, /.ssh/my-key-pair.pub (Linux) or C: keys my-key-pair.pub (Windows). The file name extension for this file is not important. Save the private key to a different local file that has the.pem extension. If at all possible I would consider creating a new keystore in OpenSSL and new keys rather than trying to pry out the private key from the Java keystore. By opening the Java keystore and extracting the private key one is moving beyond the designed security features.
Java, PKCS12, keystore, tutorial.PKCS12 is an active file format for storing cryptography objects as a single file. It can be used to store secret key, private key and certificate.It is a standardized format published by RSA LaboratoPixelstech, this page is to provide vistors information of the most updated technology information around the world. May 15, 2009 Java has this notion of its own keystore, and Sun will give you the keytool command with Java, but that doesn’t do you much good outside of Java world. Creating the keypair. We are going to create a keypair, saving it in openssl’s preferred PEM format.

Performance
Performance greatly depends on the bit size of the generated private key. With 1024 bits you get a key in 0.5s-2s, with 2048 bits it takes 8s-20s, on the same machine. As this will block the event loop while generating the key,make sure that's ok or to spawn a child process or run it inside a webworker.
Pro Tip: authorized_keys
@maxogden found out how to use this module to create entries for the authorized_keys file:
API
keypair([opts])
Get an RSA PEM key pair.
opts can be
bits: the size for the private key in bits. Default: 2048.e: the public exponent to use. Default: 65537.
Installation
With npm do

Generating Server Certificate and Server Private Key
The following procedures generate the server certificate and server private key that BI components acting as servers must possess. The server certificate and private key is used by Oracle BI Cluster Controller, Oracle BI Server, Oracle BI Scheduler, Oracle BI Presentation Services and Oracle BI Presentation Services Plug-in (ISAPI) components.
Generating Server Certificate Request and Private key
Use the following procedure to generate the server certificate request and private key.
Advantages Of Private Key Encryption
To generate the server certificate request and private key
- Run the following command:
req -new -keyout $ServerKeyFilename -out $ServerRequestFilename -days $ValidityPeriod -config openssl.cnf
For example:
OpenSSL> req -new -keyout server-key.pem -out server-req.pem -days 365 -config openssl.cnf
This example generates the following dialog:

writing new private key to 'server-key.pem'
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
-----You are about to be asked to enter information that will be incorporated into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Some-Organization Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:
Email Address []:Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []: - Enter a Distinguished Name as prompted. The Distinguished Name identifies the server.
- Make a note of the passphrase that you entered. This passphrase is needed to decrypt the private key.
The command generates the server private key file called server-key.pem and the certificate request (unsigned server certificate) called server-req.pem.
Creating the Server Certificate
The certificate request created above can be submitted to a commercial CA to generate a server certificate. For testing purposes, the CA generated in the step Creating the Certificate Authority (CA) Certificate can be used to sign the request, as described in the following procedure.
Proshow producer 5 crack. To create the server certificate
- Run the following command:
ca -policy policy_anything -out $ServerCertFilename -config openssl.cnf -infiles $ServerRequestFilename
For example:
Openssl>ca -policy policy_anything -out server-cert.pem -config openssl.cnf -infiles server-req.pem
For this example, the following dialog is received:
Using configuration from openssl.cnf
Loading 'screen' into random state - done
Enter pass phrase for ./private/cakey.pem:
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName :PRINTABLE:'US'
stateOrProvinceName :PRINTABLE:'CA'
localityName :PRINTABLE:'Redwood Shores'
organizationName :PRINTABLE:'Oracle'
organizationalUnitName:PRINTABLE:'BI'
commonName :PRINTABLE:'Server Certificate'
Certificate is to be certified until Dec 29 07:06:45 2007 GMT (365 days)
Sign the certificate? [y/n]:y1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated - When prompted, enter the passphrase for the private key of the CA.
This is the passphrase that was supplied when creating the private key cakey.pem in the topic Creating the Certificate Authority (CA) Certificate.
Generate Pem File
This command generates the server certificate named server-cert.pem. The private key of the CA was used to sign the request. The public key is generated and placed in $DIRnewcerts with a filename that reflects the serial number, for example, 01.pem.
