Subject: [PATCH] [downstream] Remove 3des support

Completely remove support for all DES3 enctypes (des3-cbc-raw,
des3-hmac-sha1, des3-cbc-sha1-kd).  Update all tests and documentation
to user other enctypes.  Mark the 3DES enctypes UNSUPPORTED and retain
their constants.

Last-updated: 1.20-final
[antorres@redhat.com: remove diffs for:
     - src/kdamin/testing/proto/kdc.conf.proto
     - src/lib/kadm5/unit-test/api.current/chpass-principal-v2.exp
     - src/lib/kadm5/unit-test/api.current/get-principal-v2.exp
     - src/lib/kadm5/unit-test/api.current/randkey-principal-v2.exp
 since they were removed by Remove-TCL-based-libkadm5-API-tests.patch]
[jrische@redhat.com: restore supportedCMSTypes (not using 3DES any more):
    - src/plugins/preauth/pkinit/pkinit_crypto.h
    - src/plugins/preauth/pkinit/pkinit_crypto_openssl.c
    - src/plugins/preauth/pkinit/pkinit_clnt.c]

-	How to use the Kerberos encryption library.
-
-			Revised		10/15/85	spm
-
-1)	The following include file is needed:
-	
-	/projects/auth/include/des.h	(VAX)
-	---------------					(PC8086)
-
-2)	The encryption library that should be linked to is:
-	
-	/projects/auth/lib/libdes.a		(VAX)
-|	/projects/auth/ibm/lib/libdes.a	(PC8086 cross-compilation environment)
-
-3)	For each key that may be simultaneously active,
-	allocate (either compile or malloc) a "Key_schedule" struct, 
-	defined in "des.h"
-
-4)	Create key schedules, as needed, prior to using the encryption
-	routines, via "des_set_key()".
-
-5)  Setup the input and output areas.  Make sure to note the restrictions
-	on lengths being multiples of eight bytes.
-
-6)	Invoke the encryption/decryption routines, "ecb_encrypt()"
-	 or "cbc_encrypt()"
-
-7)	To generate a cryptographic checksum, use "cbc_cksum()"

-int
-	des_set_key(k,schedule)
-		C_Block			*k;
-		Key_schedule	schedule;
-
-	Calculates a key schedule from (all) eight bytes of the input key, and
-	puts it into the indicated "Key_schedule" struct;
-
-	Make sure to pass valid eight bytes, no padding or other processing
-	it done.
-
-	The key schedule is then used in subsequent encryption/decryption
-	operations.  Many key schedules may be created and cached for later
-	use.
-
-	The user is responsible to clear keys and schedules no longer needed
-	to prevent their disclosure.
-
-|	Checks the parity of the key provided, to make sure it is odd per
-|	FIPS spec.  Returns 0 value for key ok, 1 for key_parity error.

-
-This is the low level routine that encrypts or decrypts a single 8-byte
-block in electronic code book mode.  Always transforms the input
-data into the output data.
-
-If encrypt is non-zero, the input (cleartext) is encrypted into the
-output (ciphertext) using the specified key_schedule, pre-set via "des_set_key".
-
-If encrypt is zero, the input (now ciphertext) is decrypted into
-the output (now cleartext).
-
-Input and output may be the same space.
-
-Does not return any meaningful value.  Void is not used for compatibility

-
-
-	If encrypt is non-zero, the routine cipher-block-chain encrypts
-	the INPUT (cleartext) into the OUTPUT (ciphertext) using the provided
-	key schedule and initialization vector.  If the length is not an integral
-	multiple of eight bytes, the last block is copied to a temp and zero 
-	filled (highest addresses).  The output is ALWAYS an integral multiple
-	of eight bytes.
-
-	If encrypt is zero, the routine cipher-block chain decrypts the INPUT
-	(ciphertext) into the OUTPUT (cleartext) using the provided key schedule
-	and	initialization vector.	Decryption ALWAYS operates on integral
-	multiples of 8 bytes, so will round the length provided up to the
-	appropriate	multiple. Consequently,	it will always produce the rounded-up
-	number of bytes of output cleartext. The application must determine if
-	the output cleartext was zero-padded due to cleartext lengths not integral
-	multiples of 8.
-
-	No errors or meaningful value are returned.  Void is not used for
-	compatibility with other compilers.

-	int				length;		/* in bytes						*/
-	Key_schedule	schedule;	/* precomputed key schedule	   */
-	C_Block			*ivec;		/* 8 bytes of ivec			   */
-
-
-	Produces a cryptographic checksum, 8 bytes, by cipher-block-chain
-	encrypting the input, discarding the ciphertext output, and only retaining
-	the last ciphertext 8-byte block.  Uses the provided key schedule and ivec.
-	The input is effectively zero-padded to an integral multiple of
-	eight bytes, though the original input is not modified.
-
-	No meaningful value is returned.  Void is not used for compatibility
-	with other compilers.

-int
-	random_key(key)
-
-	C_Block	*key;
-
-	The start for the random number generated is set from the current time
-	in microseconds, then the random number generator is invoked
-	to create an eight byte output key (not a schedule).  The key
-	generated is set to odd parity per FIPS spec.
-
-	The caller must	supply space for the output key, pointed to 
-	by "*key", then after getting a new key, call the des_set_key() 
-	routine when needed.
-
-	No meaningful value is returned.  Void is not used for compatibility
-	with other compilers.

-
-/* string_to_key --------------------------------------------*/
-
-int
-	string_to_key(str,key)
-	char		*str;
-	C_Block	*key;
-
-	This routines converts an arbitrary length, null terminated string
-	to an 8 byte DES key, with each byte parity set to odd, per FIPS spec.
-
-	The algorithm is as follows:
-
-|	Take the first 8 bytes and remove the parity (leaving 56 bits).
-|	Do the same for the second 8 bytes, and the third, etc.  Do this for
-|	as many sets of 8 bytes as necessary, filling in the remainder of the

-/* read_password -------------------------------------------*/
-
-read_password(k,prompt,verify)
-	C_Block	*k;
-	char *prompt;
-	int	verify;
-
-This routine issues the supplied prompt, turns off echo, if possible, and
-reads an input string.  If verify is non-zero, it does it again, for use
-in applications such as changing a password. If verify is non-zero, both
-versions are compared, and the input is requested repeatedly until they
-match.  Then, the input string is mapped into a valid DES key, internally
-using the string_to_key routine.  The newly created key is copied to the
-area pointed to by parameter "k".  
-
-No meaningful value is returned.  If an error occurs trying to manipulate
-the terminal echo, the routine forces the process to exit.
-
-/* get_line ------------------------*/
-long get_line(p,max)
-	char	*p;
-	long	max;
-
-Reads input characters from standard input until either a newline appears or
-else the max length is reached.  The characters read are stuffed into
-the string pointed to, which will always be null terminated.  The newline
-is not inserted in the string.  The max parameter includes the byte needed
-for the null terminator, so allocate and pass one more than the maximum
-string length desired.

- * Code to do a DES round using the tables.  Note that the E expansion
- * is easy to compute algorithmically, especially if done out-of-order.
- * Take a look at its form and compare it to everything involving temp
- * below.  Since SP[0-7] don't have any bits in common set it is okay
- * to do the successive xor's.
- *
- * Note too that the SP table has been reordered to match the order of
- * the keys (if the original order of SP was 12345678, the reordered
- * table is 71354682).  This is unnecessary, but was done since some
- * compilers seem to like you going through the matrix from beginning
- * to end.
- *
- * There is a difference in the best way to do this depending on whether
- * one is encrypting or decrypting.  If encrypting we move forward through
- * the keys and hence should move forward through the table.  If decrypting
- * we go back.  Part of the need for this comes from trying to emulate
- * existing software which generates a single key schedule and uses it
- * both for encrypting and decrypting.  Generating separate encryption
- * and decryption key schedules would allow one to use the same code
- * for both.
- *
- * left, right and temp should be unsigned DES_INT32 values.  left and right
- * should be the high and low order parts of the cipher block at the
- * current stage of processing (this makes sense if you read the spec).
- * kp should be an unsigned DES_INT32 pointer which points at the current
- * set of subkeys in the key schedule.  It is advanced to the next set
- * (i.e. by 8 bytes) when this is done.
- *
- * This occurs in the innermost loop of the DES function.  The four
- * variables should really be in registers.
- *
- * When using this, the inner loop of the DES function might look like:
- *
- *      for (i = 0; i < 8; i++) {
- *              DES_SP_{EN,DE}CRYPT_ROUND(left, right, temp, kp);
- *              DES_SP_{EN,DE}CRYPT_ROUND(right, left, temp, kp);
- *      }
- *
- * Note the trick above.  You are supposed to do 16 rounds, swapping
- * left and right at the end of each round.  By doing two rounds at
- * a time and swapping left and right in the code we can avoid the
- * swaps altogether.
