Mary used a substitution cipher, to decode Mary Queen of Scots cipher Frequency analysis was used.
That means looking for letters (or symbols) that have the same number of appearances in the cypher text as common letters in the language the plain text message is thought to be in. E is very common in english, so are the other vowels, you make some educated guesses and start to fill in words which gets you the meaning of more symbols and so on.
Treasonous is simply a matter of opinion. (She was quite possibly set up!)

What is the diffie-hellman cipher?
Diffie-Hellman is not as much a cipher as a means of securing exchanging keys. You would use it to securely notify someone else of a symmetric shared key that you both would use for encrypting data. Think of it as more a key exchange method utilizing public and private keys than an actual cipher methodology.
What does sipher mean?
Do you mean cipher? A cipher is a method of encrypting in which a different figure (another letter, a number, a glyph of some kind) is substituted for each letter. A very simple cipher involves replacing the letters with a number being the number of the alphabetic order of the letter, so A becomes 1, B becomes 2 and C becomes 3, and so on. In this cipher 1-14-19-23-5-18-19 is Answers.
What is cryptography?
Cryptography (or cryptology) is the practice and study of hiding information. It is the method of taking any data, mathematically scrambling it into gibberish, yet allow for decryption back into the original data. It is spelled cryptography. In computer Network Cryptography means The science and art of manipulating messages to make them secure is called cryptography.
What is a birthday attack?
A birthday attack is a method of code decryption which exploits the birthday paradox - that which explains that within a class of 30 students, there is an assumed probability of two sharing the same birthday of 70 percent.
Why cryptology is a fast-growing profession?
Until modern times cryptography referred almost exclusively to encryption, which is the process of converting ordinary information (called plaintext) into unintelligible gibberish (called ciphertext).[7]Decryption is the reverse, in other words, moving from the unintelligible ciphertext back to plaintext. A cipher (or cypher) is a pair of algorithms that create the encryption and the reversing decryption. The detailed operation of a cipher is controlled both by the algorithm and in each instance by a key. This is a secret parameter (ideally known only to the communicants) for a specific message exchange context. A "cryptosystem" is the ordered list of elements of finite possible plaintexts, finite possible cyphertexts, finite possible keys, and the encryption and decryption algorithms which correspond to each key. Keys are important, as ciphers without variable keys can be trivially broken with only the knowledge of the cipher used and are therefore useless (or even counter-productive) for most purposes. Historically, ciphers were often used directly for encryption or decryption without additional procedures such as authentication or integrity checks.In colloquial use, the term "code" is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a more specific meaning. It means the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, wallaby replaces attack at dawn). Codes are no longer used in serious cryptography-except incidentally for such things as unit designations (e.g., Bronco Flight or Operation Overlord)-since properly chosen ciphers are both more practical and more secure than even the best codes and also are better adapted to computers.

How do you decode to encode using md5 funcation in php?
md5() is one-way encryption method. Example: $test_string="php"; $md_encoded_string=md5($test_string); But, you can't decode the string back to php.So, if you need to check the entered string is php or not $user_entered_string=md5($_POST['user_input']); if($md_encoded_string == $user_entered_string) { echo "input matched"; }
Which method of encryption inserts characters between existing characters?
Transposition cipher is a method of encryption that reshuffles the order of characters without changing them, often inserting characters between existing characters to hide the message. This technique does not change the characters themselves, only their positions within the message.
What is video encryption?
Video Encryption is a method of preventing a video signal from being viewed unless you have the ability to decode the signal. Older methods dropped the video interlace which caused a picture to roll or skew. Newer methods change the video image so that it is scrambled and unreadable unless processed with the decryption key. Since the signal must be decrypted on each frame, this has to be done 60 times per second (in the U.S.) and 50 times per second (in Europe). This requires hardware decoding because software cannot decode the entire picture image fast enough. Satellite Television providers typically use two methods: they change the encryption key on a regular basis, and they send a disable signal to a receiver device when the subscription ends, which invalidates its stored keys and it can't read the signals.
Is 1080p TV compatible with 1080i cable?
yup it can decode 1080p all the way threw 480i (1080i included)
What is a 'one time pad'?
A one-time pad is an encryption/deencryption method where a random series of cipher codes is used one time, and one time only, in a communication. Assuming that only the two parties possess their pairs of pads, then the encryption is unbreakable.
