+ Ron Rivest's Cipher No.2
+ ------------------------
+
+Ron Rivest's Cipher No.2 (hereafter referred to as RRC.2, other people may
+refer to it by other names) is word oriented, operating on a block of 64 bits
+divided into four 16-bit words, with a key table of 64 words. All data units
+are little-endian. This functional description of the algorithm is based in
+the paper "The RC5 Encryption Algorithm" (RC5 is a trademark of RSADSI), using
+the same general layout, terminology, and pseudocode style.
+
+
+Notation and RRC.2 Primitive Operations
+
+RRC.2 uses the following primitive operations:
+
+1. Two's-complement addition of words, denoted by "+". The inverse operation,
+ subtraction, is denoted by "-".
+2. Bitwise exclusive OR, denoted by "^".
+3. Bitwise AND, denoted by "&".
+4. Bitwise NOT, denoted by "~".
+5. A left-rotation of words; the rotation of word x left by y is denoted
+ x <<< y. The inverse operation, right-rotation, is denoted x >>> y.
+
+These operations are directly and efficiently supported by most processors.
+
+
+The RRC.2 Algorithm
+
+RRC.2 consists of three components, a *key expansion* algorithm, an
+*encryption* algorithm, and a *decryption* algorithm.
+
+
+Key Expansion
+
+The purpose of the key-expansion routine is to expand the user's key K to fill
+the expanded key array S, so S resembles an array of random binary words
+determined by the user's secret key K.
+
+Initialising the S-box
+
+RRC.2 uses a single 256-byte S-box derived from the ciphertext contents of
+Beale Cipher No.1 XOR'd with a one-time pad. The Beale Ciphers predate modern
+cryptography by enough time that there should be no concerns about trapdoors
+hidden in the data. They have been published widely, and the S-box can be
+easily recreated from the one-time pad values and the Beale Cipher data taken
+from a standard source. To initialise the S-box:
+
+ for i = 0 to 255 do
+ sBox[ i ] = ( beale[ i ] mod 256 ) ^ pad[ i ]
+
+The contents of Beale Cipher No.1 and the necessary one-time pad are given as
+an appendix at the end of this document. For efficiency, implementors may wish
+to skip the Beale Cipher expansion and store the sBox table directly.
+
+Expanding the Secret Key to 128 Bytes
+
+The secret key is first expanded to fill 128 bytes (64 words). The expansion
+consists of taking the sum of the first and last bytes in the user key, looking
+up the sum (modulo 256) in the S-box, and appending the result to the key. The
+operation is repeated with the second byte and new last byte of the key until
+all 128 bytes have been generated. Note that the following pseudocode treats
+the S array as an array of 128 bytes rather than 64 words.
+
+ for j = 0 to length-1 do
+ S[ j ] = K[ j ]
+ for j = length to 127 do
+ s[ j ] = sBox[ ( S[ j-length ] + S[ j-1 ] ) mod 256 ];
+
+At this point it is possible to perform a truncation of the effective key
+length to ease the creation of espionage-enabled software products. However
+since the author cannot conceive why anyone would want to do this, it will not
+be considered further.
+
+The final phase of the key expansion involves replacing the first byte of S
+with the entry selected from the S-box:
+
+ S[ 0 ] = sBox[ S[ 0 ] ]
+
+
+Encryption
+
+The cipher has 16 full rounds, each divided into 4 subrounds. Two of the full
+rounds perform an additional transformation on the data. Note that the
+following pseudocode treats the S array as an array of 64 words rather than 128
+bytes.
+
+ for i = 0 to 15 do
+ j = i * 4;
+ word0 = ( word0 + ( word1 & ~word3 ) + ( word2 & word3 ) + S[ j+0 ] ) <<< 1
+ word1 = ( word1 + ( word2 & ~word0 ) + ( word3 & word0 ) + S[ j+1 ] ) <<< 2
+ word2 = ( word2 + ( word3 & ~word1 ) + ( word0 & word1 ) + S[ j+2 ] ) <<< 3
+ word3 = ( word3 + ( word0 & ~word2 ) + ( word1 & word2 ) + S[ j+3 ] ) <<< 5
+
+In addition the fifth and eleventh rounds add the contents of the S-box indexed
+by one of the data words to another of the data words following the four
+subrounds as follows:
+
+ word0 = word0 + S[ word3 & 63 ];
+ word1 = word1 + S[ word0 & 63 ];
+ word2 = word2 + S[ word1 & 63 ];
+ word3 = word3 + S[ word2 & 63 ];
+
+
+Decryption
+
+The decryption operation is simply the inverse of the encryption operation.
+Note that the following pseudocode treats the S array as an array of 64 words
+rather than 128 bytes.
+
+ for i = 15 downto 0 do
+ j = i * 4;
+ word3 = ( word3 >>> 5 ) - ( word0 & ~word2 ) - ( word1 & word2 ) - S[ j+3 ]
+ word2 = ( word2 >>> 3 ) - ( word3 & ~word1 ) - ( word0 & word1 ) - S[ j+2 ]
+ word1 = ( word1 >>> 2 ) - ( word2 & ~word0 ) - ( word3 & word0 ) - S[ j+1 ]
+ word0 = ( word0 >>> 1 ) - ( word1 & ~word3 ) - ( word2 & word3 ) - S[ j+0 ]
+
+In addition the fifth and eleventh rounds subtract the contents of the S-box
+indexed by one of the data words from another one of the data words following
+the four subrounds as follows:
+
+ word3 = word3 - S[ word2 & 63 ]
+ word2 = word2 - S[ word1 & 63 ]
+ word1 = word1 - S[ word0 & 63 ]
+ word0 = word0 - S[ word3 & 63 ]
+

+1.1 23/08/96 - eay
+ Changed RC2_set_key() so it now takes another argument. Many
+ thanks to Peter Gutmann <pgut01@cs.auckland.ac.nz> for the
+ clarification and origional specification of RC2. BSAFE uses
+ this last parameter, 'bits'. It the key is 128 bits, BSAFE
+ also sets this parameter to 128. The old behaviour can be
+ duplicated by setting this parameter to 1024.
+
+1.0 08/04/96 - eay
+ First version of SSLeay with rc2. This has been written from the spec
+ posted sci.crypt. It is in this directory under rrc2.doc
+ I have no test values for any mode other than ecb, my wrappers for the
+ other modes should be ok since they are basically the same as
+ the ones taken from idea and des :-). I have implemented them as
+ little-endian operators.
+ While rc2 is included because it is used with SSL, I don't know how
+ far I trust it. It is about the same speed as IDEA and DES.
+ So if you are paranoid, used Tripple DES, else IDEA. If RC2
+ does get used more, perhaps more people will look for weaknesses in
+ it.
