SP Hi,
SP I was wondering if someone could clarify this for me. I'm trying to decrypt
SP a string which has been encrypted in 3DES ECB mode.
SP I'm using the command line utility and a program I have written to do this.
SP According to the EVP_EncryptInit.html, I should use the cipher
SP EVP_des_ede3().
This is correct!
SP However in the command line utility I don't see any 3DES ECB cipher.
SP According to the 'enc' man page the cipher 'des-ede3' is an alias for
SP 'des-ede3-cbc'.
Maybe if you supply an IV then it is aliased to des-ede3-cbc ?!
SP Are both of these correct? If so, shouldn't there be a standard naming
SP convention for these ciphers? and how do I encrypt/decrypt a string in 3DES
SP EC mode using the command line utility?
openssl des-ede3 -iv 0 -other-options-here
