Comparison of Des_3des_aes_ides_rsa cipher algorithms

Symmetric encryption algorithms (also called shared keys)

Type	definition: send receive uses the same symmetric key	Secret key Length	Group length	Number of Cycles	Security
Des	Data Encryption Standard, faster, suitable for encrypting large amounts of data;	56	64	16	Dependent key Poor search method attack
3DES	is based on des symmetric algorithm, a piece of data with three different keys for three times encryption, higher intensity;	112 168	64	48	Military grade, resistant to differential analysis and correlation
Aes	Advanced Encryption Standard, symmetric algorithm, is the next generation of cryptographic algorithm standard, fast, high security level, the current implementation of AES standard is Rijndael algorithm	128 192 256	64	10 12 14	High security level, advanced Encryption Standard
Idea	International data encryption algorithms that provide very strong security with a 128-bit key	128	64	8	Attacks that can withstand differential cryptographic analysis
MD5	Information-Digest algorithm Message-digest 5	128	512	4	The MD5 algorithm is primarily designed for digital signatures
SHA	Secure Hashing algorithm Secure Hash algorithm	160	512	4	Digital signatures can be implemented, similar to MD5

Asymmetric encryption Algorithm (also known as public key)

Type	definition: a pair of public keys and private keys,	explanation Example
Rsa	Based on large prime number decomposition (Ron Rivest,adi Shamir,len Adleman Three-bit genius's name)	For example: The modulo operation of 7*d=1mod8 is: (7*d)/8 .... 1 d=7
Ecc	Elliptic Curve cipher Coding	Elliptic Curves Cryptography
