What is the first step in attempting to decode encrypted notes?

The first step in attempting to decode encrypted notes is to identify any repeating patterns or common symbols. This is crucial because many encryption methods rely on substituting letters or symbols according to specific schemes. By looking for patterns, you can start to discern if certain symbols correspond to particular letters or frequently used words in the language used for the notes, such as 'the,' 'and,' or common prefixes and suffixes.

Recognizing these patterns lays the groundwork for breaking the code, as it provides a foundational understanding of the structure of the encryption. This analytical approach can lead to hypotheses about what certain symbols represent and helps to formulate strategies for further decoding.

Counting the number of characters in the notes or assessing the length of each line may provide some insights, but those elements alone do not directly contribute to decoding the message. Similarly, checking for grammatical errors might reveal issues with the output of a message, but it does not assist in the decryption process itself. Ultimately, focusing on patterns in encryption is the most effective first step.
