Hello all!!
I have an application that interact with Linux and windows.
i have to cypher a file in Linux, and windows has to decrypt it.
I use openssl and 3des to cypher it.
openssl enc -des3 -salt -in file.txt -out 3descifr.txt -pass
pass:lidia CIPHER
openssl enc -des-ede3-cbc -d -in 3descifr.txt -out 3desdescifr.txt
-pass pass:lidia DECRYPT
Do you know if i can decrypt the file with Java??
You need to implement the relevant functionality. That means parsing
the file to get the salt and then implemeting EVP_BytesToKey() in Java using
the documented algorithm.
If i use -k instead of -pass, i think that -k option specify the key in HEX.
openssl enc -des3 -salt -in file.txt -out 3descifr.txt -k pass:lidia
Then i think that isn't necessary implement the EVP_BytesToKey(), is
this all right??
Do you know what is the padding that is used to encrypt it??
Do you know any library in Java that use the 3des algorithm??
Regards!
Steve.
