Bug #10633
Updated by nobu (Nobuyoshi Nakada) over 9 years ago
OpenSSL Cipher throws a RangeError on the update function when given a very large string. I've verified that it happens with a file of 2 or 3GB in size. 1 GB works fine. This has been tested with 2.1.2, 2.1.3, and 2.2rc-1. ```ruby require `require 'openssl' cipher = OpenSSL::Cipher::Cipher.new('aes-256-cbc') cipher.decrypt cipher.iv = "fooooooooooooooooooooooooooooooooo" cipher.key = "barrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" f = File.open("<path to a 2 GB file generated with dd>", "r") contents = f.read; cipher.update(contents) ``` cipher.update(contents)` Running this will return: ``` RangeError: `RangeError: integer 2147483648 too big to convert to `int' ``` `int'` File generated with dd: ``` dd `dd if=/dev/zero of=2g.img bs=1 count=0 seek=2G ``` seek=2G`
