Answers to Questions (FAQ)

What is Copiale Cipher? (Definition)

The Copiale code is the name given to a substitution alphabet (homophonic) discovered in a fully encrypted manuscript, whose only inscriptions are Philipp, 1866 and 'Copiales 3'.

The manuscript was decoded by a team of researchers in 2011. The content of the book describes in German language, an initiation ceremony for a secret society.

How to encrypt using Copiale cipher?

The Copiale code uses a homophonic substitution alphabet (several characters can correspond to the same starting character).

Example: COPIALE can be written char(63)char(60)char(100)char(89)char(78)char(67)char(69) or also char(63)char(38)char(100)char(121)char(72)char(67)char(65)

Here is the correspondence table found by the researchers:

Achar(80)char(78)char(72)
Ächar(48)
Bchar(81)
Cchar(63)
Dchar(62)char(122)
Echar(65)char(69)char(73)char(79)char(85)char(41)char(90)
Fchar(126)
Gchar(54)char(88)
Hchar(45)
Ichar(121)char(89)char(33)
Jchar(52)
Kchar(53)
Lchar(67)
Mchar(43)
Nchar(66)char(70)char(68)char(103)
Ochar(60)char(38)
Öchar(87)
Pchar(100)
Rchar(82)char(51)char(106)
Schar(124)char(91)
Tchar(94)
Uchar(61)char(34)
Üchar(93)
Vchar(49)
Wchar(77)
Xchar(102)
Ychar(56)
Zchar(83)
SCHchar(84)
STchar(55)
CHchar(47)
ENchar(71)
EMchar(71)
char(97)char(98)char(99)char(76)char(101)char(92)char(75)char(104)char(105)char(107)char(108)char(109)char(110)char(111)char(112)char(113)char(114)char(115)char(116)char(117)char(118)char(119)char(120)char(40)char(74)

The letter Q has no translation. The space character is systematically encoded.

How to decrypt Copiale cipher?

The decryption of the Copiale code is an inverse substitution, each character is then translated into a letter of the Latin alphabet or a space (or in rare cases, a group of letters).

There are a few exceptions: first the character char(58) seems to be used to repeat the previous letter (often a consonant). Then, several characters have no meaning: char(35)char(36)char(37)char(42)char(50)char(57)char(64)char(95)char(96)char(99)char(162)char(172)char(177)

How to recognize a Copiale ciphertext? (Identification)

The text is composed of characters from the Latin alphabet, a few Greek letters, and a minority of various glyphs.

No spaces are visible in the text (because spaces are encrypted by a letter)

Any references to a secret society, German or in Germany or to a manuscript are clues.
