AESDecrypt takes in a 16, 24, or 32 byte AES key (128, 192, 256 bit encryption respectively) and encrypted text.

AESEncrypt takes in a 16, 24, or 32 byte AES key (128, 192, 256 bit encryption respectively) and plain text.

BytesLenSplit splits the given byte array into an n-length arrays.

CIDRIsSubset returns whether na is a subset (possibly improper) of nb.

CoalesceCIDRs coalesces cidrs into a smaller set of CIDRs, by combining overlapping networks into networks of size coalesceMaskLen, if there are at least coalesceNumber cidrs in the larger mask.

CoalesceIPs combines ips into CIDRs, by combining overlapping networks into networks of size coalesceMaskLen, if there are at least coalesceNumber IPs in the larger mask.

FirstIP returns the first IP in the CIDR.

HashInts returns a SHA512 hash of ints.

IntSliceToMap creates an int set from an array.

IPToCIDR returns the CIDR containing just the given IP.

LastIP returns the last IP in the CIDR.

RangeStr returns the hyphenated range of IPs.

RemoveStrDuplicates removes duplicates from strings, considering a map of already-seen duplicates.

RemoveStrFromArray removes a specific string from a string slice.

Stacktrace is a helper function which returns the current stacktrace.

StrInArray returns whether s is one of the strings in strs.

StripAllWhitespace returns s with all whitespace removed, as defined by unicode.IsSpace.

ToNumeric returns a float for any numeric type, and false if the interface does not hold a numeric type.

ValidateAESKey takes in a byte slice and tests if it's a valid AES key (16, 24, or 32 bytes).

ConstantBackoffDuration is a fallback duration that may be used by an application along with NewConstantBackoff().

DefaultFactor may be used by applications for the factor argument.

BodyInterceptor fulfills the Writer interface, but records the body and doesn't actually write.

Interceptor implements http.ResponseWriter.

JSONNameOrIDStr is designed to handle backwards-compatibility for old Perl endpoints which accept both.

JSONIntStr unmarshals JSON strings or numbers into an int.
