John's Cryptography Blog: AES CBC or AES CTR mode剛拿到駕照的呆呆,很得意的跟小華說:「今天我開車到外面停車,路牌寫說『此 處停車不得超過一小時』」。 小華說:「那又怎樣?」 呆呆:「你知道嗎?我只花了30分鐘就停好車了!」 小華:「……」晚上睡覺時,小寶一直不肯乖乖去睡。 媽媽說:「小寶,不要再鬧了…&hIn 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 Overflow看到答案時我真的愣住了想想....原來我真的是受這樣的教育長大的啊~~看來我覺得我有必要再從小學一年級開始念起了這真的是一個好題目,多多少少也反映出我們的教育教出了頭腦多麼僵化的學生??============ ========= ========= ========= ======各位:丟給你們去ECB 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 ......

WPA2 802.11i CCM (CTR+CBC) AES IP Core - IP Cores, Inc: Security, FEC, Compression, and DSP IP Cores為什麼會用「二百五」來嘲笑他人?日常生活中,人們常把說話不正經、辦事不認真、處事隨便、好出洋相的人叫做「二百五」。但這個稱呼從何而來,卻有多種說法。----------------------------------------------------------------------------Implementation of the new WLAN security standard 802.11i requires the NIST standard AES cipher in CTR and CBC modes (a.k.a. CCM) for encryption and message authentication. The WPA2 AES core is tuned for 802.11i applications and as such requires much ......

Encrypting a file using AES in 256-bit CBC/CTR mode using the OpenSSL library | Alin Tomescu趙先生一早起來就頭痛的要死... 因為他前一天晚上喝的爛醉回家!! 他強迫自己把疲憊不堪的眼睛睜開。 睜開眼後竟然看到床頭上放了一杯水跟幾顆頭痛藥, 然後坐起身後又看到了他的衣服已經燙好、疊好在床邊。 因為一起床就看到這幾樣反常的事, 所以I’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 ....
