How does SHA-1 differ from the MD4 algorithm? A) MD4 can process 64 bits at a time B) Generally, SHA is considered a more secure hash than MD C) MD4 creates a digest length of 128 bit whereas SHA-1's digest length is 160 bits D) Flaws have not yet been discovered in the MD4 algorithm

Jan 09, 2020 · “Continued usage of SHA-1 for certificates or for authentication of handshake messages in TLS or SSH is dangerous, and there is a concrete risk of abuse by a well-motivated adversary. In last year general plan Announcing SSL Labs Grading Changes for 2017 there is a statement if server uses only Forward Secrecy ciphers the grade will go down to B. This hasn't happened yet, but currently implemented ssllabs test there is a warning that servers only supporting non-forward secrecy ciphers grade will be reduced to B from March 2018. Remarks. Both field names and values are based on the TLS Cipher Suites list from the Internet Assigned Numbers Authority (IANA). This enumeration represents values that were known at the time a specific version of .NET was released. RSA, AES and SHA can all provide encryption but for different purpose. RSA. RSA fits in in PKI asymmetric key structure. It provides message encryption and supports authentication and nonrepudiation services. However, the downside is the encryption process is much slower than symmetric key, such as AES and DES.

RSA on the other hand is faster at encryption than DSA. When decrypting, DSA is faster, mainly due to its great decryption capability. If you need digital signing, DSA is the encryption algorithm of choice. For verification of the digital signature RSA is the best choice.
