Apache Reference: mod_ssl, SSLPassPhraseDialog

SSLPassPhraseDialog

Type of Pass Phrase Dialog for Encrypted Private Keys
Syntax: SSLPassPhraseDialog A
Example: SSLPassPhraseDialog exec:bin/fetchphrase
Since: Apache 1.3

When Apache starts up, mod_ssl must read the various certificate (-> SSLCertificateFile) and private key (-> SSLCertificateKeyFile) files of the SSL-enabled virtual servers. For security reasons, the private key files are usually encrypted. Consequently, mod_ssl needs to query the administrator for a pass phrase to decrypt those files. The type argument specifies the approach taken for this query: ``builtin'' means that an interactive terminal dialog is used; ``exec:filepath'' means that filepath executes and provides the pass phrase on stdout.
