md5

I wonder how reliable the adler32 checksum is, compared to e.g. md5 checksums? It was told on wikipedia that adler32 is "much less reliable" than md5, so I wonder how much, and in which way? More specifically, I'm wondering if it is reliable enough as a consistency check for long-time archiving of (tar) files of size 20GB+? For details on the error-checking capabilities of the Adler-32 checksum, see for example Revisiting Fletcher and Adler Checksums. Maxino, 2006. This paper contains an analysis on the Hamming distance provided by these two checksums, and provides an indication of the

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 capacity, while one of the CPU cores is completely maxed-out. I have more cores available, and in the future will likely have even more cores. So far I've only been able to tap into more cores if I happen to need multiple hashes of the same file, say an MD5 AND a SHA256 at the same time. I can use the same I/O stream to feed two or more hash algorithms, and I get the faster algorithms done for

I am trying to get MD5 encrypted pass from MySQL DB via Java code (Hibernate). But I cant get neither String nor any reasonable Java type. The only thing I am getting is this unhelpful message: java.lang.ClassCastException: [B cannot be cast to com.mysql.jdbc.Blob (or whatever Java type I try cast to). Here is my method: public void testCrypto() { session.beginTransaction(); // creates native SQL query // uses native MySQL's MD5 crypto final Blob pass = (Blob) session.createSQLQuery("SELECT MD5('somePass')") .list().get(0); session.getTransaction().commit(); } Here is full stack trace: java

Is there any other module for md5? zerkms It is in hashlib import hashlib print(hashlib.md5('asd'.encode()).hexdigest()) It has been deprecated since version 2.5. You must use hashlib . From: http://www.python.org/dev/peps/pep-0004/ MD5 have been replaced by the 'hashlib' module. 来源： https://stackoverflow.com/questions/4954602/replacement-for-md5-module-in-python-3

If it's not immediately obvious, let me start by saying I am not a crypto person. I have been tasked with replicating the behavior of Java's PBEWithMD5AndDES (MD5 digest with DES encryption) in Python 2.7. I do have access to Python's cryptography toolkit PyCrypto. Here is the Java code whose behavior I am trying to replicate: import java.security.spec.KeySpec; import javax.crypto.spec.PBEKeySpec; import javax.crypto.SecretKey; import javax.crypto.SecretKeyFactory; import java.security.spec.AlgorithmParameterSpec; import javax.crypto.spec.PBEParameterSpec; import javax.crypto.Cipher; import

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center . I am calculating the md5 of a file but getting different results code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); AssetManager am = getResources().getAssets(); String as = null; try { InputStream is=am.open("sdapk.db"); as=is.toString(); }catch(IOException e) { Log.v("Error_E",""+e); }
