Hi would like to know abt this command of red hat linux
grub-md5-crypt its easy to encrypt the passwd from this command but how to store the encrypted password ,,, And again is it possible to decrypt the passwd
And also do let me know abt 'idecrypt'command is it possible to decrypt the passwd from the password
Also tell me few others algorithams or commands of any flavor that would encrypt the normal text ,,,
regs..
Hi,
MD5 is not a enryption standard it just provides a "fingerprint" or message digest of a message of arbitrary length. The difficulty of coming up with any message having a given message digest is on the order of 2^128 operations,So basically its a one way encryption but it has a known collision weakness. idecrypt is used to decrypt encrypted responses from a pidentd server with DES encryption.
grub-md5-crypt is just used to get the fingerprint of the user pass to protect grub modification
there are lots of encryption standards like blowfish ,md4,md5 ,SHA1 ,SHA2 ,DES and Triple DES, Serpent , twofish and famous CRC !!
Hope this clarify.
