# grid-change-pass-phrase(1)

Change the pass phrase of a private key

## NAME

grid-change-pass-phrase - Change the pass phrase of a private key

## SYNOPSIS

**grid-change-pass-phrase** -help \| -usage \| -version \| -versions

## DESCRIPTION

The **grid-change-pass-phrase** program changes the pass phrase 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.
