Secret text dream

from Wikipedia, the free encyclopedia

The secret , crypto , cipher or key text space is understood in cryptography as the set of all character strings ( secret texts ) that are created from the plain text space (the plain texts ) by encryption .

The size of the secret text space is important for the security of the encryption process, since a large secret text space makes brute force attacks more difficult (see also key length ).
