WebLetters To Numbers Converter 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.

In order to encrypt a plaintext letter, the sender positions the sliding ruler underneath the first set of plaintext letters and slides it to LEFT by the number of positions of the secret shift. The plaintext letter is then encrypted to the ciphertext letter on the sliding ruler underneath.
WebCiphers are typically just a set of instructions (an algorithm) for converting one set of symbols (e.g., letters) into another set of symbols (e.g., numbers or pictographs). An example of a simple letter-to-number cipher is A=1, B=2, C=3, etc. All that being said, while codes and ciphers are different, the terms are often used interchangeably. WebASCII Conversions Numbers in the following ranges can represent ASCII codes: The range 48–57 (0x30–0x39) represents digits, where 48 is '0' and 57 is '9'. The range 65–90 (0x41–0x5A) represents uppercase letters, …
