Tool to convert letters to numbers and vice versa using the alphanumeric code A1Z26 (A=1, B=2, C=3).
Convert letters to numbers in various formats. Numbering the letters so A=1, B=2, etc is one of the simplest ways of converting them to numbers. This is called the A1Z26 cipher. However, there are more options such as ASCII codes and tap codes to decode numbers.
Converts alphabet characters into their corresponding alphabet order number (e.g. A=1, B=2, …, Z=26) while non-alphabet characters are being dropped.
A monoalphabetical substitution cipher uses a fixed substitution over the entire message. The ciphertext alphabet may be a shifted, reversed, mixed or deranged version of the plaintext alphabet.
A1Z26 is very simple direct substitution cypher, where each alphabet letter is replaced by its number in the alphabet. Below is the A1Z26 encoder/decoder. Here all letters are set to lowercase, the English alphabet is used, and all non-alphabet symbols are not transformed.
Letter Numbers. Replace each letter with the number of its position in the alphabet. A simple replacment method that is usually the first one taught to children and is still an effective way to obscure your message.
Introduce children to the world of cryptography with simple code-breaking games. Using the alphabet-number pairing, create secret messages by substituting letters with their corresponding numbers (A=1, B=2, etc.). Provide the students with the coded message and a key to decode it.
Translate between letters and numbers. Letter number cipher (A1Z26) replaces each letter by the corresponding position in an alphabet (A=1, B=2, …, Z=26). Open in the editor.
A1Z26 encoder/decoder. A1Z26 is very simple direct substitution cypher, where each alphabet letter is replaced by its number in the alphabet.
ASCII (American Standard Code for Information Interchange) is a 7-bit characters code, with values from 0 to 127. The ASCII code is a subset of UTF-8 code. The ASCII code includes control characters and printable characters: digits, uppercase letters and lowercase letters. ASCII vs Unicode.
