Can anyone tell me the name of this cipher please?
I know it's a simple substitution cipher, I just don't know the name of it.

Cipher Key:

Cipher alphabet:

a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v|w|x|y|z
h|e|l|p|a|b|c|d|f|g|i|j|k|m|n|o|q|r|s|t|u|v|w|x|y|z

this is a test


Cipher text:

I think I have found the answer: a Caesar variant, a "Mixed Alphabet" substitution cipher.
Does it have a specific name?

• What are you asking? You provide one question near the top of your message, then continue to discuss a different construction of classical cipher. – figlesquidge Dec 13 '13 at 12:09
• @figlesquidge The question is still the question at the top. Is this cipher named or have I got it right and it's just called a variant of the 2 I talked about. – Chris Dec 13 '13 at 12:10
• Fair enough. In that case I think you could improve your question by removing the section below the horizontal line - if you are only asking about the first section then everything below it is superfluous. – figlesquidge Dec 13 '13 at 14:04
• You are asking "is it A or B", and the answer is "it's neither, A and B are both better (and more efficient) than this". – tylo Dec 13 '13 at 14:05
