Where n is the modulus of private and the public key It involves public key and private key, where the public key is known to all and is used to encrypt the message whereasВ private key is only used to decrypt the encrypted message. RSA is another method for encrypting and decrypting the message. In the above program, we have used simple logic for encrypting and decrypting a given string by simply adding and subtracting the particular key from ASCII value.Д®xample: C program to encrypt and decrypt the string using RSA algorithm. Str = str - 3 //the key for encryption is 3 that is subtracted to ASCII value Str = str + 3 //the key for encryption is 3 that is added to ASCII value Simple C program to encrypt and decrypt a string Similarly, for decrypting the string, 3 is subtracted from the ASCII value of the characters to print an original string. While encrypting the given string, 3 is added to the ASCII value of the characters. PlainText = base64.DecodeBase64(Encoding.Example: C program to encrypt and decrypt the string using Caesar Cypher Algorithm.ДЇor encryption and decryption, we have used 3 as a key value. use Unicode encoding type to decode base64 string use UTF8 encoding type to decode base64 string string plainText = base64.DecodeBase64() string base64 = 'cwBhAG0AcABsAGUAIABpAG4AcAB1AHQA' Also the specific encoding model is supported. If you don't type the encoding model, it will use UTF8 to decode the base64 string as default. Var bytes = Convert.FromBase64String(base64Text) Public static string DecodeBase64( this string base64Text, Encoding encoding = null) And you can select which encoding type is used to decode your base64 string, not only UTF8. Null checks for input string make the function more executable.

Now we will make an extension method to decode a base64 string.

One liner code for decoding a base64 string in C#: string plainText = (Convert.FromBase64String( 'c2FtcGxlIGlucHV0')) use Unicode encoding type to encode a base64 stringД«ase64 = plainText.EncodeBase64(Encoding.Unicode) use UTF8 encoding type to encode a base64 string string base64 = plainText.EncodeBase64() Or you can input target encoding type, such as Unicode. If the encoding type is missing, it will use the UTF8 as default. So you can call the EncodeBase64() extension method to encode a plain text to base64 string. Var bytes = encoding.GetBytes(plainText) Public static string EncodeBase64( this string plainText, Encoding encoding = null) You need check whether the input string is null value, and need to support different types of encodings, besides UTF8. It's better to create an extension method to encode a base64 string. One liner code for encoding a base64 string in C#: string base64 = Convert.ToBase64String(( 'sample input'))
