This is fixed by changed the in line 41 of the file pkcs7_padding.c the returned value to be the buffer_size. Web"Cannot find any provider supporting AES/CBC/PKCS7Padding" Does this mean that I won't be able to encrypt in Java and decrypt using Crypto++ because they can't use a mutually compatible padding system, or is there another one I can use that is supported by both systems? Is it not possible to configure Crypto++ to use "PKCS5Padding"? Thanks again,

WebInstall the module with: npm install pkcs7 var pkcs7 = require('pkcs7'), encrypted; // pad a buffer! enctcrypted = encrypt(pkcs7.pad(buffer)); // later, you can unpad it: console.log('the secret is out! ' + pkcs7.unpad(decrypt(encrypted))); Install with cli command $ npm install -g pkcs7 $ pkcs7 --help $ pkcs7 --version Documentation OpenSSL uses PKCS7 padding by default. This padding means when your data is not a multiple of the block size, you pad n bytes of the value n, where n is however many bytes you need to get to the block size. AES's block size is 16.
