At first, I'm sorry for my poor English. I wish you can understand this. In swift4, how can I encode String to sha3-512?Or, can I use any api to get value?
happened to read about a service that checks a password against commonly used / breached ones.
https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/
A given password is hashed (SHA-1) and then the first 5 characters of the hash is compared against the commonly used ones. This service is exposed via API. This could mean that the first 5 digits of the hash is exposed to the outside world. Isn't that a risk the API users are taking?What is the probability of finding the possible passwords (eg: rainbow tables) if the first 5 digits of the SHA-1 hashed value is known?
I was implementing an HTTPS client/server example just for learning purpose using the book "Implementing SSL / TLS Using Cryptography and PKI" by Joshua Davies. It contains an example implementation with C source code. I just tried to build a HTTPS client using that source code. But, in tls.c file it uses two macros MD5_BYTE_SIZE
and SHA1_BYTE_SIZE
and I can't see any values defined for these macros in that book. I tried with permutations of 16,24,32 for both macros but failed in SSL handshaking, and greater values causes segmentation fault. I hope if anybody familiar with this book can help me
What is the best way to create a SHA-1 for a very large file in pure Java6? How to implement this method:
public abstract String createSha1(java.io.File file);
I am using php mysqli_connect
for login to a MySQL database (all on localhost)
<?php//DEFINE ('DB_USER', 'user2');//DEFINE ('DB_PASSWORD', 'pass2');DEFINE ('DB_USER', 'user1');DEFINE ('DB_PASSWORD', 'pass1');DEFINE ('DB_HOST', '127.0.0.1');DEFINE ('DB_NAME', 'dbname');$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);if(!$dbc){ die('error connecting to database'); }?>
MySQL Server ini File:
[mysqld]# The default authentication plugin to be used when connecting to the serverdefault_authentication_plugin=caching_sha2_password#default_authentication_plugin=mysql_native_password
with caching_sha2_password
in the MySQL Server ini file, it's not possible at all to login with user1 or user2;
error: mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in...
with mysql_native_password
in the MySQL Server ini file, it's possible to login with user1, but with user2, same error;
how can I login using caching_sha2_password
on the mySql Server?
