How does RSA work while encrypting a sentence?
How does RSA work while encrypting a sentence?
this will help Neither. In practice RSA is almost always coupled with a symmetric cipher such as AES to encrypt larger ciphertext.RSA in itself certainly doesn't distinguish between words and sentences. RSA - the cryptographic primitive - operates on

Code signing of embedded firmware: Is a CRC enough when the firmware is encrypted?
Code signing of embedded firmware: Is a CRC enough when the firmware is encrypted?
it fixes the issue Since the firmware comes encrypted, in my opinion a simple CRC check on the flash content should be sufficient to prove the firmware validity. But I'm no expert for cyber security, so... do I need more?

I hope this helps you . No - It only prevents rainbow table attacks. As a attacker needs to build the rainbow table for each password entry. Because the salt adds a lil spice which differentiates the password hash from all the others. Dictionary-base

Is the amount of bytes in a Unicode character always 1-4, or can it be a different length?
This might help you If your Unicode is 1 to 4 bytes, then I assume you are using UTF-8 encoding; it is certainly common.UTF-8 code points can be 1, 2, 3 or 4 bytes long, with distinct patterns to the bytes to help you recognise them.
