Passphrase protection of private key
Thanks.
I am able to persist the data. I just don't want anyone else to read the private key from the file. I am looking for something like PEM_write_RSAPrivateKey available in openssl for C. It has parameters to specify the passphrase and the passphrase needs to be correctly given while trying to read back. For Java I am using java.security package for generating keys and encrypting and decrypting. I could not find a function that uses a passphrase. I need an API that will write to a file and use a passphrase to protect the private key.

NAME
grid-change-pass-phrase - Change the passphrase of a private key
SYNOPSIS
grid-change-pass-phrase [-help] [-usage] [-version] [-versions]
grid-change-pass-phrase [-file PRIVATE-KEY]
DESCRIPTION
The grid-change-pass-phrase program changes the passphrase protecting a private key or PKCS12 bundle containing a private key and
certificate. By default, grid-change-pass-phrase uses the X509_USER_KEY environment variable to locate the private key. If that is not set,
then it looks for $HOME/.globus/userkey.pem and $HOME/.globus/usercred.p12 in succession. The path to a key can be specified by using the
-file command-line option.
The full set of command-line options to grid-change-pass-phrase are:
-help, -usage
Display the command-line options to grid-change-pass-phrase and exit.
-version, -versions
Display the version number of the grid-change-pass-phrase command. The second form includes more details.
-file PRIVATE-KEY
Change the passphrase of the private key named by PRIVATE-KEY instead of the default.
EXAMPLES
Change the passphrase of the default private key:
% grid-change-pass-phrase
Enter pass phrase for /home/juser/.globus/userkey.pem:
writing RSA key
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
ENVIRONMENT VARIABLES
The following environment variables affect the execution of grid-change-pass-phrase:
X509_USER_KEY
Path to the default private key file.
