Subject: Add base64tohex to allow values to be written to IP addresses, integers etc
X-Git-Tag: release_2_2_1~247
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f1c71a4b67aae8d9ab060f2ae974f14642f967aa;p=thirdparty%2Ffreeradius-server.git

Add base64tohex to allow values to be written to IP addresses, integers etc

Remove base64tostr (will add tostring expansion later)

Rename strtobase64 to tobase64
