What is the relationship between "SHA-2" and "SHA-256"
2015年4月29日 · In light of SHA-3, it would be better if the SHA-2 variants had been called SHA2-224, SHA2-256 etc. as was done with the SHA-3 variants, but they aren't commonly, so oh well. SHA-1 doesn't come in multiple sizes, so SHA- n where n …
What is the difference between “SHA-2” and “SHA-256”
2015年10月14日 · The SHA-2 family consists of multiple closely related hash functions. It is essentially a single algorithm in which a few minor parameters are different among the variants. The initial spec only covered 224, 256, 384 and 512 bit variants.
Does a SSL certificate created using rsa:2048 use an SHA-2 ...
2015年8月28日 · It might even re-sign the same certificate which was once signed with SHA-1 now with SHA-2. Currently most (all?) public CA use SHA-2 because SHA-1 is phased out for security reasons. In your case you use the openssl req command to create not only a certificate request but also sign it, i.e. create a self-signed certificate. Modern versions of ...
What's the difference between the hash algorithms SHA-2 and …
However, while a real world collision attack on SHA-1 was finally demonstrated in 2017, the feared attacks on SHA-2 have failed to materialize. It's nowadays generally accepted that breaking SHA-2 won't be as easy as it seemed ten years ago, and thus all the variants of SHA-2 are still considered secure for the foreseeable future.
What's the state of support for SHA-2 in various platforms?
2010年3月9日 · Most platforms now support the SHA-2 family. However, SHA-1 is still used in many applications, like SSL, and will be in use for a while. A competition for "SHA-3" is well underway. It might be reasonable to jump from SHA-1 to the new SHA-3 standard when it arrives.
SSL encryption, SHA-1 and SHA-2 - Stack Overflow
2015年9月3日 · The SHA-224, SHA-256, SHA-384 and SHA-512 functions are colloquially known as "SHA-2", so "SHA-2" is not one function, but a family of four hash functions. The TLS specification defines cipher suites .
Check if my SSL Certificate is SHA1 or SHA2 - Stack Overflow
2014年10月29日 · In addition, SHA-1 support was removed by most modern browsers and operating systems in early 2017. Any new certificate you get should automatically use a SHA-2 algorithm for its signature. Legacy clients will continue to accept SHA-1 certificates, and it is possible to have requested a certificate on December 31, 2015 that is valid for 39 months.

2015年6月22日 · Yeah, OK, I didn't read the title all the careful, you should mention the "-2" part in your question as well. Don't know if there is a SHA-2 512-bit implementation in .NET but probably is. – Lasse V. Karlsen
What's the difference between SHA and AES encryption?
2013年8月28日 · SHA is a family of "Secure Hash Algorithms" that have been developed by the National Security Agency. There is currently a competition among dozens of options for who will become SHA-3, the new hash algorithm for 2012+. You use SHA functions to take a large document and compute a "digest" (also called "hash") of the input.
