The glibc2 version of this function supports additional encryption algorithms.
If salt is a character string starting with the characters "$id$" followed by
a string terminated by "$":
$id$salt$encrypted
then instead of using the DES machine, id identifies the encryption method
used and this then determines how the rest of the password string is
interpreted. The following values of id are supported:
ID | Method
---------------------------------------------------------
1 | MD5
2a | Blowfish (not in mainline glibc; added in some
| Linux distributions)
5 | SHA-256 (since glibc 2.7)
6 | SHA-512 (since glibc 2.7)
So $5$salt$encrypted is an SHA-256 encoded password and $6$salt$encrypted is
an SHA-512 encoded one.
"salt" stands for the up to 16 characters following "$id$" in the salt. The
encrypted part of the password string is the actual computed password. The
size of this string is fixed:
MD5 | 22 characters
SHA-256 | 43 characters
SHA-512 | 86 characters
The characters in "salt" and "encrypted" are drawn from the set [a-zA-Z0-9./].
In the MD5 and SHA implementations the entire key is significant (instead of
only the first 8 bytes in DES).
기본적으로 sha-512 또는 그 밖의 다른 시스템의 섀도 파일에서 md5 암호를 계속 사용할 수 있습니다. toolpasspass 와 같은 명령을 사용하여 MD5 해시를 생성 할 수 있습니다.
Debian / Ubuntu에서 whois 패키지의 일부인 mkpasswd를 사용할 수 있습니다. mkpasswd -m sha-512
