-   * FEE_KEY_VERSION 3, FEE_KEYSTRING_VERSION 1
-
-CryptKit-10
-   -- Added KeyStringFormat.doc
-   -- Deleted -publicKeyData, keyWithPublicKeyData (public keys now always
-      represented as strings)
-   -- Beefed up range and validity checking in:
-         -- hexstr_to_giant()
-	 -- new_hexstr_from_key()
-	 -- +keyWithPublicKeyString
-   -- Added check for valid_hexstr() and NULL hexstr_to_key() in

-      as ObjC files
-
-CryptKit-11
-   * FEE_KEYSTRING_VERSION = 2
-     FEE_KEYSTRING_VERSION_MIN = 1

-
-CryptKit-12
-   * Alpha version sent to REC 6 Sep 1996 and to dreece 12 Sep 96

-    -- Added debugging code to DES.c, MD5.c
-    -- Added mersennePrimes[24..26]

-CryptKit-17
-    -- New curveParams mechanism, with IEEE-approved curve parameters
-    -- Old curve param 'a' is 'c'; new params b, c, x1OrderPlus x1OrderMinus
-    -- This version doesn't *use* the new curve params in elliptic algebra;
-       it's an interim version for testing. DVT suite (ckutils/cktest) still
-       works at depths 0 thru 4.
-    -- NO API CHANGES since CryptKit-16.
-    -- key strings and signatures still compatible with CryptKit-16 and
-       JavaFEE-4
-    -- Deleted mersennePrimes[], set_crypt_params(), new_public_com(),
-       key_copy()
-    -- Most fields in keystruct now superceded by curveParams *cp

-     signatures.
-   * FEE_SIG_VERSION = 3
-   * PUBLIC_KEY_STRING_VERSION = 3
-   * Old 2:1 FEED renamed feeFEEDExp (feeFEEDExp.c, names start with
-     feeFEEDExp). New 1:1 FEE is feeFEED.c. A #define in feeFEED.h redirects
-     client's feeFEED calls to feeFEEDexp
-   -- New elliptic math using all curveParams fields
-   -- Cleaned up all which_curve/twist code to use CURVE_MINUS/CURVE_PLUS
-   -- plus curves now used exclusively except for in FEED decrypt, which
-      uses both curves
-   -- Moved all byteRep code from utilities.c to byteRep.c.
-   -- Added curveOrderJustify(), use it to trim private key data and
-      signature random data to [2, curveOrder]
-   -- curveParams[4] now has full parameters
-   -- ENGINE_127_BITS version, with hard-coded 127 bit elliptic() in
-      engineNSA127.c, no longer builds - obsolete (hopefully)
-   -- Fixed negation bug in gmersennemod() (a long-standing FEE bug)
-   -- Fixed n[words-1] == 0 bug in extractbits() (ditto)
-   -- Added keyWithPrivateString:depth:usageName: to NSFEEPublicKey
-   -- Deleted obsolete #defines from NSFastEllipticCurve.c, including those
-      for signature_compare()
-   -- Added FEE_PROFILE logic
-   -- Now have unified giant-to-byteRep mechanism via serializeGiant and
-      deserializeGiant. Deleted canonicalize_ints(), canonicalize_shorts(),
-      giant_cleanse(), data_to_giant()
-   -- Removed all *_to_hexstr and hexstr_to* code
-
-CryptKit-19

-     JavaFEE-5.
-   * Integrated in cryptdev master 13 Feb 1997.
-   -- Broke backward compatibility with CipherFiles. CFILE_VERSION = 1.
-   -- First working 1:1 FEED, in feeFEED.c. Old 2:1 FEED, now in feeFEEDExp.c,
-      unchanged.
-   -- Fixed zero bug in gcompg().
-   -- CipherFile uses portable byte rep; added CFE_FEED and CFE_FEEDExp types

-   -- Added maxShorts and minBytes to curveParams
-   -- Added explicit SIGN_PLUS, SIGN_MINUS as 's' arg to elliptic_add()
-   -- newGiant() no longer modifies CurrentMaxShorts or giant stack
-   -- Added FEE_DEPTH_192_M529891
-   -- Added feeFEEDCipherTextSize(), feeFEEDExpCipherTextSize()
-   -- Fixed platform dependencies in MD5.c
-   -- All borrowGiant() calls in NSFastEllipticCurve,c specify explicit
-      giant size (usually curveParams.maxShorts)
-   -- #ifdef'd out matric math routines in NSGiantIntegers.c
-   -- Added FEE_DEPTH_192_M529891
-   -- CurveParams.c now assumes all fields have valid giants
-   -- feeCipherfile now has four encrTypes - CFE_PublicDES, CFE_RandDES,
-      CFE_FEED, CFE_FEEDExp
-
-CryptKit-20
-   * Integrated in cryptdev master 20 Feb 1997.
-   -- CipherFile - was {key1,key2}, is {sendPubKey,otherKey}
-   -- Broke out common defines into CipherFileTypes.h
-   -- NSCipher returns nil properly on otherKeyData, sigSata, sendPubKeyData
-   -- Added enc64WithLines; dec64 ignores all whitespace
-   -- Broke out encrType-specific functions in CipherFile{FEED,DES}
-
-CryptKit-21
-   * Integrated in cryptdev master 7 Mar 1997.
-   * Sent to REC 7 Mar 1997.
-   -- Added curve depth = 3; q=40, k=213

-      feeFEEEDExp. This is an incompatible change! But I don't think anyone
-      was using the last version....
