John's Cryptography Blog: AES CBC or AES CTR mode有人說,香蕉買回來要掛起來放這樣會容易保存,因為香蕉以為自己還沒被從樹上摘下來! In symmetric encryption sometimes it's hard to decide which mode to use. Especially between AES CBC mode and AES CTR (Counter) mode. Here are some pro and cons of these two modes: Padding: CBC requires message padding, CTR does not Speed: Both ......

How to choose an AES encryption mode (CBC ECB CTR OCB CFB)? - Stack OverflowECB should not be used if encrypting more than one block of data with the same key. CBC, OFB and CFB are similar, however OFB/CFB is better because you only need encryption and not decryption, which can save code space. CTR is used if you want good ......

Encrypting a file using AES in 256-bit CBC/CTR mode using the OpenSSL library | Alin TomescuI’ve been using OpenSSL a *LOT* for work lately and I’ve learned some interesting stuff. Here’s a quick guide on how to encrypt and decrypt files using AES in CBC or CTR mode using 256 bit keys and 128 bits IVs. To do this, I used the EVP API in OpenSSL ....
