there is a similar issue reported https://github.com/cloudfoundry/credhub-cli/issues/86

the problem is that any argument starting with a dash is interpreted as a flag.

there should be a way to escape dashes, maybe adding support for the GNU -- "end of options" CLI convention would be a good idea, so we could have

$ credhub set -t password -n '/example-password' -w -- '-supersecret'

right now the only workaround I found is to use import with a temp file

https://github.com/cloudfoundry/credhub-cli/blob/main/EXAMPLES.md#exporting-and-importing

which is a kludge and may leave plain text secrets on the filesystem

a simpler workaround: use stdin instead

$ echo '-supersecret' | credhub set -t password -n '/example-password'
