6 Crypto::setEncryptionIvec - Set application Ivec
7
9 Void setEncryptionIvec( [Int] ivec )
10
12 ivec The new ivec. This must be an array of integers, containing
13 exactly 16 integers between 0 and 255. An Exception will be thrown if
14 the parameter is unsuitable. The ivec is not secret and does not need
15 to be generated in any particular way.
16
18 Sets the application Ivec used by Crypto.encode (3kaya) and
19 Crypto.decode (3kaya) to a new value for the remainder of program exe‐
20 cution. You can obtain the key from a variety of sources (e.g. a flat
21 file, or a database entry) - the easiest way is probably to read 16
22 bytes from a file with IO.getChar (3kaya)
23 The Ivec is not secret, but in some cases you may need it to be con‐
24 sistent.
25 Web applications should call this function from within their webconfig
27 function to avoid unpredictable results. Also to avoid unpredictable
28 results, this function may only be called once per program run, and
29 must be called before any other function that uses the key. An Excep‐
30 tion will be thrown if this is called for a second time or too late.
