+
+// This section implements a checksum algorithm for descriptors with the
+// following properties:
+// * Mistakes in a descriptor string are measured in "symbol errors". The higher
+// the number of symbol errors, the harder it is to detect:
+// * An error substituting a character from 0123456789()[],'/*abcdefgh@:$%{} for
+// another in that set always counts as 1 symbol error.
+// * Note that hex encoded keys are covered by these characters. Xprvs and
+// xpubs use other characters too, but already have their own checksum
+// mechanism.
+// * Function names like "multi()" use other characters, but mistakes in
+// these would generally result in an unparseable descriptor.
+// * A case error always counts as 1 symbol error.
+// * Any other 1 character substitution error counts as 1 or 2 symbol errors.
+// * Any 1 symbol error is always detected.
+// * Any 2 or 3 symbol error in a descriptor of up to 49154 characters is always detected.
+// * Any 4 symbol error in a descriptor of up to 507 characters is always detected.
+// * Any 5 symbol error in a descriptor of up to 77 characters is always detected.
+// * Is optimized to minimize the chance a 5 symbol error in a descriptor up to 387 characters is undetected
+// * Random errors have a chance of 1 in 2**40 of being undetected.
+//
+// These properties are achieved by expanding every group of 3 (non checksum) characters into
+// 4 GF(32) symbols, over which a cyclic code is defined.
+
+/*
+ * Interprets c as 8 groups of 5 bits which are the coefficients of a degree 8 polynomial over GF(32),
+ * multiplies that polynomial by x, computes its remainder modulo a generator, and adds the constant term val.
+ *
+ * This generator is G(x) = x^8 + {30}x^7 + {23}x^6 + {15}x^5 + {14}x^4 + {10}x^3 + {6}x^2 + {12}x + {9}.
+ * It is chosen to define an cyclic error detecting code which is selected by:
+ * - Starting from all BCH codes over GF(32) of degree 8 and below, which by construction guarantee detecting
+ * 3 errors in windows up to 19000 symbols.
+ * - Taking all those generators, and for degree 7 ones, extend them to degree 8 by adding all degree-1 factors.
+ * - Selecting just the set of generators that guarantee detecting 4 errors in a window of length 512.
+ * - Selecting one of those with best worst-case behavior for 5 errors in windows of length up to 512.
+ *
+ * The generator and the constants to implement it can be verified using this Sage code:
+ * B = GF(2) # Binary field
+ * BP.<b> = B[] # Polynomials over the binary field
+ * F_mod = b**5 + b**3 + 1
+ * F.<f> = GF(32, modulus=F_mod, repr='int') # GF(32) definition
+ * FP.<x> = F[] # Polynomials over GF(32)
+ * E_mod = x**3 + x + F.fetch_int(8)
+ * E.<e> = F.extension(E_mod) # Extension field definition
+ * alpha = e**2743 # Choice of an element in extension field
+ * for p in divisors(E.order() - 1): # Verify alpha has order 32767.
+ * assert((alpha**p == 1) == (p % 32767 == 0))
+ * G = lcm([(alpha**i).minpoly() for i in [1056,1057,1058]] + [x + 1])
+ * print(G) # Print out the generator
+ * for i in [1,2,4,8,16]: # Print out {1,2,4,8,16}*(G mod x^8), packed in hex integers.
+ * v = 0
