I am trying to implement SHA-2 encryption instead of SHA-1. For this, I know that the number of bits between these two hash algorithms are different, and it confuses me.
If I have a packet of data that is encrypted yet also includes a sha-224 checksum that is not encrypted, am I creating a security vulnerability?
I\'m trying to implement a Chord distributed hash table. I want to开发者_JAVA技巧 use SHA-1 as the hash function to generate node ids and map values to the DHT. However, I\'ll need to use numerical op
Conclusion: SHA-1 is safe against preimage attacks, however it is easy to compute, which means it is easier to mount a bruteforce or dictionary attack. (The same is true for successors like SHA-256.)
Is calculating an MD5 hash less CPU intensive than SHA-1 or SHA-2 on \"standard\" laptop x86 hardware? I\'m interested in general information, not specific to a certain chip.
I\'m interested in optimizing the hashing of some large files (optimizing wall clock time).The I/O has been optimized well enough already and the I/O device (local SSD) is only tapped at about 25% of
I am trying to sign a token object using SHA1. I am using bouncycastle as the security provider. Whenever the program tries to sign something it gives me this error.
I don\'t mean for this to be a debate, but I\'m trying to understand the technical rationale behind why so many apps use SHA1 for hashing secrets, when SHA512 is more secure. Perhaps it\'s simply for
I have a SHA1 password and PasswordSalt in my aspnet_Membership table. but, when I run a query from the server (a Sql Query), the reader reveals
Is behavior of SHA-1 algorithm defined for Unicode strings? I do realize that SHA-1 开发者_运维知识库itself does not care about the content of the string, however,
