These are undocumented functions used by the cf admin. The syntax is exactly
the same as the standard encrypt() functions.
You can use this code with the standard encrypt functions to make the
strings db safe.
This produces a db safe string
<cfset secret_word_encrypted=
toBase64(encrypt("#string2beEncrypted#","#key#"))>
This decrypts the string
<cfset secret_word_decrypted=
decrypt(tostring(tobinary("#secret_word_encrypted#")),"#key#")>
