System and method for high speed reversible data encryption

A method for facilitating decryption of encrypted data, comprising the steps of:

• locating an encryption key;
• locating a character in the encryption key to provide a located character;
• determining a number of characters in the encrypted data;
• obtaining a first shifting amount;
• shifting a position of the located character in the encryption key by the obtained first shifting amount to determine a shifted position of the located character in the encryption key, wherein the shifted position is located at a position in the encryption key that is the located character shifted by the obtained first shifting amount;
• translating a character in the data with the character located at the shifted position to provide a decrypted character;
• and
• repeating the steps of obtaining, shifting, and translating for a second shifting amount different from the first shifting amount, for at least one remaining character in the data in order to provide decrypted data.

A system for facilitating encryption of data using an encryption key, comprising:

• a computer including a memory for storing the data and the encryption key and a processor for processing the data;
• and
• an application program stored in the memory and accessible by the processor for directing processing of the data by the processor, wherein the application program is configured for:
• locating an encryption key;
• locating a character in the encryption key to provide a located character;
• determining a number of characters in the data;
• obtaining a first shifting amount;
• shifting a position of the located character in the encryption key by the obtained first shifting amount to determine a shifted position of the located character in the encryption key, wherein the shifted position is located at a position in the encryption key that is the located character shifted by the obtained first shifting amount;
• translating a character in the data with the character located at the shifted position to provide an encrypted character;
• and
• repeating the steps of obtaining, shifting, and translating for a second shifting amount different from the first shifting amount, for at least one remaining character in the data in order to provide encrypted data.
