Several common hash encryption methods

Common hash encryption (from a foreign Forum)

--------------- * Nix series ------------------------
System: ES (Unix)
Example: IvS7aeT4NzQPM
Note: in Linux or other Linux kernel Systems
Length: 13 characters
Description: 1st and 2 bits are salt. In this example, 'iv 'is salt, followed by hash value.

System: MD5 (Unix)
Example: $1 $12345678 $ xm4p3prkbgknn1_g9p0t/
Note: in Linux or other Linux kernel Systems
Length: 34 characters
Description: The $1 $ bit at the beginning is the encryption flag. The next 8-bit 12345678 is the salt used for encryption, and the next is the hash.
Encryption Algorithm: 2000 cyclic calls MD5 Encryption

SHA-512 (Unix)
Example: $6 $12345678 $ U6Yv5E1lWn6mEESzKen42o6rbEm
Note: in Linux or other Linux kernel Systems
Length: 13 characters
Description: The $6 $ bit at the beginning is the encryption mark, the last 8 bits are salt, and the next is hash.
Encryption Algorithm: 5000 times of SHA-512 Encryption

SHA-256 (Unix)
Example: $5 $12345678 $ jBWLgeYZbSvREnuBr5s3gp13vqi
Note: in Linux or other Linux kernel Systems
Length: 55 characters
Description: The $5 $ bit at the beginning is the encryption mark, the last 8 bits are salt, and the next is hash.
Encryption Algorithm: 5000 times of SHA-256 Encryption

System: MD5 (APR)
Example: $ apr1 $12345678 $ auQSX8Mvzt. tdBi4y6Xgj.
Note: in Linux or other Linux kernel Systems
Length: 37 characters
Description: The $ apr1 $ bit at the beginning is the encryption mark, the last 8 bits are salt, and the next is hash.
Encryption Algorithm: 2000 cyclic calls MD5 Encryption

----------------- Windows ------------------------------------------
System: windows
Example: Admin: b474d48cdfc4974d86ef4d24904cdd91
Length: 98 characters
Encryption Algorithm: MD4 (MD4 (Unicode ($ pass). Unicode (strtolower ($ username )))

------------------ Mysql --------------------------------------------
System: mysql
Example: 606717496665 bcba
Note: Earlier MySql versions
Length: 8 bytes (16 characters)
Note: two bytes are included, and the value of each word cannot exceed 0x7fffffff.

System: MySQL5
Example: * E6CC90B878B948C35E92B003C792C46C58C4AF40
Note: the latest version of MySQL
Length: 20 bytes (40 BITs)
Encryption Algorithm: SHA-1 (SHA-1 ($ pass ))

------------------ Other systems ---------------------------------------------

System: MD5 (WordPress)
Example: $ P $ B123456780BhGFYSlUqGyE6ErKErL01
Note: md5 used by WordPress
Length: 34 characters
Description: $ P $ indicates the encryption type, followed by one character, often 'B', followed by eight salts, followed by hash
Encryption Algorithm: 8192 md5 cyclic Encryption

System: MD5 (phpBB3)
Description: phpBB 3. x. x.
Example: $ H $ 9123456785DAERgALpsri. D9z3ht120
Length: 34 characters
Description: $ H $ at the beginning is the encryption mark followed by a character. Generally, it is a '9' character, then an 8-bit salt, and then a hash value.
Encryption Algorithm: 2048 cyclic calls MD5 Encryption

System: RAdmin v2.x
Description: Remote Administrator v2.x
Example: 5e32cceaafed5cc80866737dfb212d7f
Length: 16 bytes (32 characters)
Encryption Algorithm: After the character is filled with 0 to 100 bytes, the filled characters are encrypted by md5 (32-bit value)

------------------------ Md5 encryption --------------------------------------------

Standard MD5
Example: c4ca4238a0b923820dcc509a6f75849b
Scope of use: phpBB v2.x, before version 1.0.13 of Joomla, and other cmd
Length: 16 characters
Other additions and variants are similar:

Md5 ($ pass. $ salt)
Example: 6f04f0d75f6870858bae14ac0b6d9f73: 1234

Md5 ($ salt. $ pass)
Example: f190ce9ac8445d249747cab7be43f7d5: 12

Md5 (md5 ($ pass ))
Example: 28c8edde3d61a0411511d3b1866f0636

Md5 (md5 ($ pass). $ salt)
Example: 6011527690eddca23580955c216b1fd2: wQ6

Md5 (md5 ($ salt). md5 ($ pass ))

Md5 (md5 ($ salt). $ pass)
Example: 816a14db44578f516cbaef25bd8d8296: 1234

Md5 ($ salt. $ pass. $ salt)
Example: a3bc9e11fddf4fef4deea11e33668eab: 1234

Md5 ($ salt. md5 ($ salt. $ pass ))
Example: 1d715e52285e5a6b546e442792652c8a: 1234
