URL and hash extraction, De Bruijn sequences

URLs Extractor finds addresses with a protocol such as https. Bare hostnames do not meet that rule. Choose sorting for an ordered report, or unique results when repeated addresses add no value. Keep duplicates when occurrence counts matter. Extraction does not visit an address, check its response, or establish whether it is safe.

Hashes Extractor matches hexadecimal strings by character length. It accepts uppercase and lowercase hexadecimal letters, then returns lowercase matches. Select the expected length instead of collecting every supported length when you know the source format. A matching token can be an identifier rather than a digest. The extractor neither identifies the algorithm nor verifies the original data. Read the hex dump section to convert a hexadecimal character count into a byte count.

De Bruijn Sequence Generator builds a sequence from alphabet size and key length. It does not search your pasted text. Start with small parameters because the output grows rapidly. Use the sequence to test overlapping patterns, not as a random password or encryption key.
