The encryption methods described are symmetric key block ciphers.

Data Encryption Standard (DES) is the predecessor, encrypting data in 64-bit blocks using a 56 bit key. Each block is encrypted in isolation, which is a security vulnerability.

Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2. These keys may be related.

DES and 3DES are usually encountered when interfacing with legacy commercial products and services.

AES is considered the successor and modern standard. <a href="http://en.wikipedia.org/wiki/Advanced_Encryption_Standard">http://en.wikipedia.org/wiki/Advanced_Encryption_Standard</a>

I believe the use of Blowfish is discouraged.

It is highly recommended that you do not attempt to implement your own cryptography and instead use a high-level implementation such as GPG for data at rest or SSL/TLS for data in transit. Here is an excellent and sobering video on encryption vulnerabilities <a href="http://rdist.root.org/2009/08/06/google-tech-talk-on-common-crypto-flaws/">http://rdist.root.org/2009/08/06/google-tech-talk-on-common-crypto-flaws/</a>

blocks|key|942703|text|AES是对称加密算法，而RSA是非对称(或公钥)加密算法。在AES中使用单个密钥进行加密和解密，而在RSA中使用单独的密钥(公钥和私钥)。128位AES密钥的强度大致相当于2600位RSA密钥。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|942704|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

AES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in AES, while you use separate keys (public and private keys) in RSA. The strength of a 128-bit AES key is roughly equivalent to 2600-bits RSA key.

DES is the old "data encryption standard" from the seventies.

Does anyone have pros and cons together for comparing these encryption algorithms ?

有谁在比较这些加密算法时有正反两方面的意见吗？
