encrypt - encrypt data

SYNOPSIS

<encrypt $data $key>

DESCRIPTION
The encrypt function encrypts each value of $data using the corresponding $key value. There must be one or more values of $data and $key; if fewer values of $key exist than $data, the last $key value is re-used.

DIAGNOSTICS
encrypt returns each value of $data, encrypted Unix style, using key $key.

EXAMPLE

<encrypt $data $pass>
<SQL "insert into secret values(counter, $ret)"> </SQL>

CAVEATS
The encrypt function was added Oct. 25 1996.

The encryption algorithm uses only the first 8 bytes of each key. The returned encrypted data is likely to be binary, but will not contain nul (ASCII zero) values.
