HOW DNAPASS WORKS

DNAPASS GENERATES PASSWORDS USING DNA-INSPIRED SEQUENCES:

SEQUENCE SELECTION

DNAPASS uses two sets of DNA-inspired sequences:

  • PRIMARY SEQUENCES: A list of 200 DNA sequences derived from biological motifs, including ambiguous characters (e.g., 'N', 'R'). Selected with a 90% probability.
  • SECONDARY SEQUENCES: A smaller set of 8 sequences restricted to the nucleotides A, T, C, and G, selected with a 10% probability.

AMBIGUITY RESOLUTION

Primary sequences often contain ambiguous characters defined by the IUPAC nucleotide code. These are resolved randomly using a predefined mapping:

  • 'N': Random choice from ['A', 'T', 'C', 'G']
  • 'R': Random choice from ['A', 'G']
  • 'Y': Random choice from ['C', 'T']
  • And so on...

CHARACTER DIVERSITY

To ensure password strength, DNAPASS enforces:

  • Uppercase Letters: At least 10% of the password length (minimum 1)
  • Lowercase Letters: At least one lowercase letter
  • Digits: At least 2 digits for passwords < 50 characters, or 3 for ≥ 50 characters
  • Special Characters: At least 4 special characters from a predefined set
  • No Spaces: Any spaces are removed

ENTROPY CONSIDERATIONS

The entropy of a DNAPASS-generated password is influenced by:

  • Sequence Selection: With 200 primary and 8 secondary sequences
  • Ambiguity Resolution: Each ambiguous character has multiple possible outcomes
  • Character Modifications: Adding digits, special characters, and case variations
  • Random Shuffling: Ensures no predictable structure

For a 12-character password, DNAPASS typically achieves entropy above NIST's 80-bit recommendation for high-security passwords.

SECURITY NOTES

DO NOT ATTEMPT TO MEMORIZE THE PASSWORDS GENERATED BY THIS TOOL. INSTEAD, USE A RELIABLE PASSWORD MANAGER, SUCH AS BITWARDEN, WHICH I PERSONALLY RECOMMEND.

THE ONLY PASSWORD YOU SHOULD MEMORIZE IS THE MASTER PASSWORD FOR YOUR PASSWORD MANAGER'S VAULT, CREATED WITH A STRONG COMBINATION OF UPPERCASE AND LOWERCASE LETTERS, NUMBERS, AND SPECIAL CHARACTERS.

ENABLE TWO-FACTOR AUTHENTICATION (2FA) WHENEVER POSSIBLE TO ENHANCE SECURITY.
