A practical guide to CRYPTA
Adapted from the supplied CRYPTA v64 package. Original emblem preserved; publication artwork derives from that emblem.
What CRYPTA does—and what it cannot establish
CRYPTA is a browser laboratory for reproducible number transformations, alphabet mappings, byte encodings and password-based encryption. The installed interface adapts the supplied v64 package. Start with Discover to compare two decimal strings, then open the tool menu for specialized laboratories. The mathematical engines are deterministic; the running application does not send your inputs to a language model.
A valid transformation establishes only that the stated rules produce the displayed result. It does not establish the original author, a secret message, intent, coordination or historical authenticity. Short strings admit many interpretations. Searching additional bases, operations, segmentations and dictionary words increases the opportunities for coincidence. Treat the trace and its assumptions as the result, not the most suggestive word.
Alphabet mappings and a reproducible first example
English A1Z26 assigns A=1 through Z=26. Spanish A1Z27 includes Ñ at position 15, so O=16 and Z=27. These are selected mapping conventions, not universal cryptographic standards. Choose the intended alphabet before comparing results; the same numeric token can identify different letters in the two alphabets. Accents and unsupported characters follow each tool’s stated normalization rules. Preserve the original input separately when transcription matters.
In the cipher laboratory, separated tokens preserve boundaries and a slash represents a space. For example, English 8 5 12 12 15 maps to HELLO. Without separators, several tokenizations can be valid, so the segmentation interface returns bounded candidates rather than a unique answer. In Discover, choose the maximum number of decoded letters separately from wildcard count. Those controls constrain different stages and are not interchangeable.
Compare numbers, wildcard words and explainable bridges
Enter a first and second number in Discover. Adjacent-digit multiplication is optional; a reading produced after multiplication must retain that assumption in its trace. The bundled lexicon is a small demonstration dictionary, not a complete English or Spanish dictionary. Add relevant words in the dictionary field when necessary, using commas, spaces or newlines. A missing result can reflect dictionary coverage or search limits rather than mathematical impossibility.
Wildcards add letters before or after a contiguous decoded fragment. Select prepend, append, and exact-count behavior explicitly. A word bridge connects two independently decoded fragments to the same dictionary word. It does not assert numeric equality or that either source intentionally encoded the word. Select a path, inspect its equations and lexical steps, and copy the JSON report to retain the settings and assumptions. Decoder catalog entries distinguish implemented methods from reference-only or configuration-dependent entries.
Arithmetic paths, reverse searches and finite limits
Adjacent operations act on neighboring digits of the current input, then concatenate their results for the next round where supported. For example, multiplying the adjacent pairs in 237 produces 6 and 21, concatenated as 621. This differs from multiplying the whole integer by another integer. Record operator order, rounds, leading-zero behavior and any insertion or deletion hypothesis. An edited digit is an explicit assumption, not recovered evidence.
Reverse arithmetic is generally many-to-one. A recorded forward envelope permits replay and consistency checking, but an editable envelope is not a digital signature or authenticated evidence. Ciphertext-only reverse tools enumerate candidates within finite source-length and resource bounds. Graph tools expose nodes and equations; some deduplicate by value while others retain alternative derivations. Do not equate a bounded search with an exhaustive search over all possible transformations.
Radix, Unicode and byte encodings are different operations
The radix converter represents integers with explicit digit alphabets and exact BigInt arithmetic. Standard positional bases 2–62 use ordered digits 0–9, A–Z and a–z. Above base 36, letter case distinguishes values. Invalid digits are rejected instead of silently reinterpreted. A custom alphabet must contain unique symbols and must be retained with the output for reproducibility.
Positional base-64 representation is not RFC 4648 Base64 encoding of bytes. Use the byte tools for UTF-8 hexadecimal, binary, Base64 and Base64URL round trips. Unicode inspection distinguishes code points from UTF-8 and UTF-16 sequences; an emoji may occupy several bytes. Neither a base change nor Base64 provides confidentiality. These tools help examine representations, not recover a password or defeat modern encryption.
Calibration, null models and uncertainty
Choose target words and analysis settings before examining a result. Calibration laboratories compare observations with a specified random baseline and expose the seed and trial count. The Research tool runs its simulation in a cancellable browser worker; changing an input invalidates earlier findings and cancels an outdated simulation. Export the settings with the result rather than reporting an isolated probability.
A simulation estimates behavior under its chosen model. Uniform random digits and digit permutations are different null hypotheses and may be inappropriate for dates, addresses or human-selected numbers. Post-hoc word selection and multiple searches undermine a naive significance interpretation. The Evidence tool illustrates Bonferroni and Benjamini–Hochberg adjustments, but entering subjective p-values does not create valid statistical evidence. No output establishes intent or provenance.
Encryption, document handling and device privacy
The encrypted-file tool uses browser AES-256-GCM with PBKDF2-SHA256 password derivation, a fresh random salt and a fresh nonce. It is separate from the alphabet and arithmetic tools. Download the encrypted envelope, retain it safely, then select that file and enter the same password to decrypt it. A lost password cannot be recovered by this website. Use a strong unique password and test recovery with a non-sensitive sample before relying on any workflow. File names and MIME metadata in the supplied envelope format are not encrypted.
Documents are processed in browser memory; this installation does not connect the package’s optional cloud-storage adapter. File encryption is limited to 14 MiB plaintext and decryption to 20 MiB encrypted input. Manual image review is not OCR. Discover saves non-secret inputs and preferences in this browser; do not enter sensitive personal information or real encryption credentials there. Historical cipher keys remain in memory, not saved preferences. Site navigation still uses the website’s existing analytics and contact controls, so local mathematical processing is not a promise of zero website telemetry.
Exports, installation and source limitations
CSV and JSON exports retain bounded findings and the available transformation steps. Keep the original input, alphabet, search bounds and dictionary alongside an export. Technical method identifiers and mathematical trace text may retain the supplied English vocabulary so they remain comparable across editions. Downloaded files are copies on your device; changing a preference later does not update an earlier export.
Browser installation is optional and depends on the browser and device. The installation control displays guidance when no native prompt is available. This integrated release does not promise offline operation: shared website resources and navigation still need a connection. The package also includes administrative forensic-library adapters, but this installation does not activate an administrative event collector or publish evidence to external services. The public laboratories do not establish legal chain of custody, independent security certification or comprehensive dictionary coverage.
