The Blowfish object can be used to do encryption and decryption using
the Blowfish keyed, symmetric block cipher.
Example encryption and decription; key := "secret" data := "this is a message" encryptedData := Blowfish clone setKey(key) encrypt(data) decryptedData := Blowfish clone setKey(key) decrypt(encryptedData)Or using the stream API: key := "secret" data := "this is a message" cipher = Blowfish clone cipher setIsEncrypting(true) cipher setKey(key) cipher beginProcessing cipher inputBuffer appendSeq(data) cipher process cipher endProcess encryptedData := cipher outputBuffer cipher = Blowfish clone cipher setIsEncrypting(false) cipher setKey(key) cipher beginProcessing cipher inputBuffer appendSeq(encryptedData) cipher process cipher endProcess decryptedData := cipher outputBuffer | ||
beginProcessing
Sets the key from the key slot and initializes the cipher.
decrypt(aSequence)
Returns an decrypted version of aSequence.
encrypt(aSequence)
Returns an encrypted version of aSequence.
endProcessing
Finish processing remaining bytes of inputBuffer.
inputBuffer
Returns the input buffer.
outputBuffer
Returns the output buffer.
process
Process the inputBuffer and appends the result to the outputBuffer.
The processed inputBuffer is emptied except for the spare
bytes at the end which don't fit into a cipher block.
setIsEncrypting(aBool)
If aBool is true, encrypting mode is on, otherwise, decrypting mode is on.
