Hello everybody,

My question is:
I want to use triple DEC encryption method in my application. But I don't
know which library can I use. My application is developed in VB6 a I need to
encrypt and decrypt password for login to this application. 

I'm looking at function:
void DES_ede3_cbc_encrypt(const unsigned char *input, unsigned char *output,
                          long length, DES_key_schedule *ks1,
                          DES_key_schedule *ks2, DES_key_schedule *ks3,
                          DES_cblock *ivec, int enc)  

but I dont understand this what are ks1,ks2 and ks2.

Can somebody help me to explain how to proceed to encrypt/decrypt my
password with some key ?
I need to achieve the result as by command line:
openssl enc -des3 -in pass.dec -out pass.enc -pass pass:1111 

Thanks
