About PolarSSL files into lwIP PPP support
|
||||
------------------------------------------
|
||||
|
||||
This folder contains some files fetched from the PolarSSL project for
|
||||
ciphers and encryption methods we need for lwIP PPP support.
|
||||
|
||||
The PolarSSL files were cleaned to contain only the necessary struct
|
||||
fields and functions needed for lwIP.
|
||||
|
||||
|
||||
The PolarSSL API was not changed at all, so if you are already using
|
||||
PolarSSL you can choose to skip the compilation of the included PolarSSL
|
||||
library into lwIP:
|
||||
|
||||
The following define are available for flexibility:
|
||||
|
||||
LWIP_INCLUDED_POLARSSL_MD4_C ; Use lwIP internal PolarSSL for MD4
|
||||
LWIP_INCLUDED_POLARSSL_MD5_C ; Use lwIP internal PolarSSL for MD5
|
||||
LWIP_INCLUDED_POLARSSL_SHA1_C ; Use lwIP internal PolarSSL for SHA1
|
||||
LWIP_INCLUDED_POLARSSL_DES_C ; Use lwIP internal PolarSSL for DES
|
||||
|
||||
If set (=1), the default if required by another enabled PPP feature unless
|
||||
explicitely set to 0, using included lwIP PolarSSL.
|
||||
|
||||
If clear (=0), using external PolarSSL.
|
||||
|
||||
Undefined if not needed.
|
||||
|
||||
Beware of the stack requirements which can be a lot larger if you are not
|
||||
using our cleaned PolarSSL library.
