Hi,

camellia\_rb version 1.2 released.  
It supported ruby 1.9.1 rc1.

camellia\_rb is a Camellia package for Ruby.  
Camellia is a symmetric key block cipher developed jointly  
in 2000e$B!!e(Bby world top class encryption researchers  
at NTT and Mitsubishi Electric Corporation.

Camellia has been internationally recognized,  
for example the selection project on the European  
recommendation of strong cryptographic primitives,  
NESSIE, evaluated Camellia to have  
“many similarities to the AES, so much of the analysis  
for the AES is also applicable to Camellia.”

Supported key length : 128bit/192bit/256bit  
Supported modes of operation : ECB/CFB/CBC  
license : see License.txt

# changes

from version 1.1

- It corresponded to ruby-1.9.1-rc1.
- ‘RSTRING()-\>len’ is changed to ‘RSTRING\_LEN()’.
- ‘RSTRING()-\>ptr’ is changed to ‘RSTRING\_PTR()’.
- This version is tested in ruby 1.8.5, 1.8.7 and 1.9.1 rc1  
environment.
- In the version before ruby 1.8.5 that can not use  
RSTRING\_LEN/RSTRING\_PTR, then they are automatically  
defined using RSTRING internally.
