Another typo

Typo

Clarify the operation of the SessionCryptoPassphrase directive as raised by rpluem. When SessionCryptoCertificateFile is set, asymmetrical encryption will be used, and SessionCryptoPassphrase will be interpreted as the passphrase protecting the private key. When SessionCryptoCertificateFile is not set, symmetrical encryption is used, and SessionCryptoPassphrase will contain the key to use. Make sure that the engine parameter is properly passed into the crypto functions, and fix a missing cleanup on an error case.

mod_session_crypto: Add a session encoding implementation capable of encrypting and decrypting sessions wherever they may be stored. Introduces a level of privacy when sessions are stored on the browser.
