Decode Base58 Bitcoin Alphabet Stream is a function module by Alex Stevovich / Midnight Citylights — Restores text from Base58 encoding by converting valid Bitcoin alphabet symbols back to their original form.

Decode Base64 Block Padded is a function module by Alex Stevovich / Midnight Citylights — Translates Base64 text with block padding back to its decoded UTF-8 representation.

Decode BaseN Stream is a function module by Alex Stevovich / Midnight Citylights — Reverses Base-N encoding by interpreting each character in a given alphabet as a positional value, reconstructing the original UTF-8 text.

Encode Base58 Bitcoin Alphabet Stream is a function module by Alex Stevovich / Midnight Citylights — Converts input text into Base58 form, excluding characters like 0, O, I, and l for greater visual clarity and compatibility across systems.

Encode Base64 Block Padded is a function module by Alex Stevovich / Midnight Citylights — Converts UTF-8 text into Base64, padding output blocks as needed to maintain proper structure for decoding.

Encode BaseN Stream is a function module by Alex Stevovich / Midnight Citylights — Transforms text into a Base-N encoded representation where the provided character set defines the numeric base. Works with arbitrary alphabets including experimental symbol sets.

Exponentiate Alpha-Index Chain is a function module by Alex Stevovich / Midnight Citylights — Maps A–Z to numeric indices (1–26) and raises each value to the next in order, producing exponential numeric structures derived from text sequences.

Exponentiate Alpha-Index Chain Group is a function module by Alex Stevovich / Midnight Citylights — Combines letter indices into grouped numeric blocks (A=1–Z=26) and exponentiates them in order. The group size changes how quickly and in what structure the resulting number expands.

Exponentiate Integer Chain is a function module by Alex Stevovich / Midnight Citylights — Raises each digit of a number to the power of the next in sequence, forming a rapidly growing exponential chain.

Generate Hash SHA-256 is a function module by Alex Stevovich / Midnight Citylights — Calculates the SHA-256 digest of a given string, returning a 64-character hexadecimal representation. The hash is irreversible and serves as a unique digital fingerprint of the input data.

Generate Random Integer is a function module by Alex Stevovich / Midnight Citylights — Produces a random integer between two numeric bounds. The inputs are automatically normalized so that order does not matter, and bias is avoided through rejection sampling.

Generate Random String is a function module by Alex Stevovich / Midnight Citylights — Creates a randomized string of the specified length using characters from a user-defined set. Random values are derived from the server’s entropy endpoint to ensure even distribution.

Generate UUID-V4 is a function module by Alex Stevovich / Midnight Citylights — Creates a version-4 universally unique identifier using randomized hexadecimal values. UUIDs provide a convenient way to generate non-colliding identifiers for data, objects, or sessions.

Generate UUID-V5 is a function module by Alex Stevovich / Midnight Citylights — Generates a deterministic version-5 UUID derived from a namespace UUID and a name string using SHA-1 hashing. The same inputs always yield the same identifier.

Get Current Day of the Week is a function module by Alex Stevovich / Midnight Citylights — Retrieves the local day name—Monday through Sunday—based on the device’s current date and timezone.

Get Entropy Bits is a function module by Alex Stevovich / Midnight Citylights — Calculates theoretical information capacity in bits from symbol count and message length.

Get String Length is a function module by Alex Stevovich / Midnight Citylights — Calculates the number of characters in a provided string.

Linear Interpolate is a function module by Alex Stevovich / Midnight Citylights — Interpolates linearly between inputs A and B. The parameter α defines proportional blending—0 returns A, 1 returns B, and intermediate values yield points between them.

Repeat String is a function module by Alex Stevovich / Midnight Citylights — Repeats the provided string a chosen number of times and concatenates the result directly without separators.

Reverse String is a function module by Alex Stevovich / Midnight Citylights — Reverses a string character-by-character while preserving spacing, punctuation, and symbols.
