Old TeX can only hyphenate words from one font and therefore you need to squeeze all the characters you use (including all accented ones) into one font.
#Text encoding differences how to
You need an input encoding to tell TeX how to interpret the contents of your text file, you need an font encoding for proper hyphenation.

Only authorized users (who have secret keys) can decrypt the encrypted data.Įncoding is used for maintaining the data usability.Įncryption is used for maintaining data confidentiality.Your text -> TeX -> PDF To decrypt the encrypted data, a secret key is required. To decode the encoded data, no key is required. It is the process of converting plain text to encrypted (cipher) text.Īs compared to encryption, encoding is the easier process.Īs compared to encoding, encryption is the more difficult process. It is the process of converting plaintext data from one form to another form.
Differences between encoding and encryption Encoding Major differences have been highlighted in the below section. Encoding and decoding are widely used in data transfer and for data storage.Įncoding/decoding are altogether a different process and should not be confused with encryption/decryption. As the name says, decoding is exactly the reverse process of encoding. Decodingĭecoding is the process of extracting the information from encoded data. As a good practice, no sensitive data should be sent using encoding. Base64 is very trivial to break, thus making it simple for an attacker to get sensitive data from encoded data. It has been commonly observed that the Base64 encoding algorithm is used for sending the data. ASCII encoding is the most widely used encoding format. The major purposes of developing encoding are data transmission, data storage and data compression/decompression. In encoding, we use sequences of characters such as letters, numbers and other special characters into a specialized format for easier transmission. Encoding is the process of converting plaintext data from one form to another. EncodingĮncoding was implemented in 1973 by scholar Stuart Hall. Cryptanalysts decode and decipher messages for political, law enforcement and military agencies. The analysis of cryptosystem, ciphertext and ciphers is called cryptanalysis.
Some of the widely used encryption algorithms:Ī cryptanalyst is someone who analyzes and decrypts the encrypted data, even without having knowledge of the decryption key. A few algorithms are symmetric, while others are asymmetric. There are many algorithms available for encryption and decryption. In decryption, the receiver receives the data (ciphertext) and then converts it into plaintext. In encryption, the sender encrypts the data and then sends to the receiver.
It converts the ciphertext into plaintext. It converts the plaintext into ciphertext. Difference between encryption and decryption EncryptionĮncryption is a process in which a plaintext message is converted into encrypted form.ĭecryption is a process in which an encrypted message is converted into its plaintext form.Įncryption takes place at the sender’s end.ĭecryption takes place at the receiver’s end.
