  • encryption - SHA, RSA and the relation between them - Information . . .
    RSA is actually two algorithms, one for asymmetric encryption, and one for digital signatures (the signature algorithm is traditionally -- but incorrectly -- described as "encryption with the private key" and this is an endless source of confusion) Asymmetric encryption uses keys Keys are parameters to the algorithm; the algorithm itself is the same for everybody (in software terms, it is
  • RSA-Based Signature Algorithms - Information Security Stack Exchange
    From Beginning Cryptography with Java - chapter 4, digital signatures: Signatures are created using the RSA algorithm by applying the RSA algorithm using the private key and then distributing the
  • How to encrypt plain message with RSA - Cryptography Stack Exchange
    Other kludgier RSA-based encryption schemes such as RSAES-OAEP try hard to shoehorn certain classes of messages, like up to 256-bit keys, into $\mathbb Z n\mathbb Z$, which are the ‘padding schemes’ you sometimes hear of
  • RSA maximum bytes to encrypt, comparison to AES in terms of security?
    RSA, as defined by PKCS#1, encrypts "messages" of limited size With the commonly used "v1 5 padding" and a 2048-bit RSA key, the maximum size of data which can be encrypted with RSA is 245 bytes No more When you "encrypt data with RSA", in practice, you are actually encrypting a random symmetric key with RSA, and then encrypt the data with a symmetric encryption algorithm, which is not
  • SHA 1 with RSA for ssl certificate
    Hi using SHA 1 with RSA encryption for ssl certificate is secure? As i know, sha 1 is not secure, but if we use RSA with sha1, still it will be an issue? Please suggest if any security issues exist
  • Can you explain Bleichenbachers CCA attack on PKCS#1 v1. 5?
    When something with RSA, using PKCS#1 v1 5, the data that is to be encrypted is first , then the padded value is converted into an integer, and the RSA modular exponentiation (with the public exponent) is applied Upon decryption, the modular exponentiation (with the exponent) is applied, and then the padding is removed The core of Bleichenbacher's attack relies on an : the attack works if
  • FIPS 140-2 compliance and RSA encryption - Cryptography Stack Exchange
    I remember reading that the RSA algorithm was only permitted for encryption when used to encrypt a symmetric key (essentially leading to hybrid encryption) However, reading through Annex A: Approved Security Functions for FIPS PUB 140-2 this doesn't seem to be an option
  • Why is padding used for RSA encryption given that it is not a block . . .
    Blocks of RSA are exactly the size of the modulus - padding (modulus exponentiation will always result in a number of modulus or less) In the block you normally encrypt a random symmetric data key, which is used to encrypt the actual plain text
  • Is there any particular reason to use Diffie-Hellman over RSA for key . . .
    RSA is two algorithms, one for asymmetric encryption, and one for digital signatures These are two distinct beast; although they share the same core mathematical operation and format for keys, they do different things in different ways Diffie-Hellman is a key exchange algorithm, which is yet another kind of algorithm
