Password hashing is a one-way process of securing plain text password by creating a bit string of a fixed size called hash using cryptographic hash function. Cryptographic hash functions designed to be a one-way function, that is, a function which is infeasible to invert.
As per wiki, Bcrypt is a password hashing function designed by Niels Provos and David Mazires, based on the Blowfish cipher. Bcrypt uses adaptive hash algorithm to store password, which is a one-way hash of the password. BCrypt internally generates a random salt while encoding passwords and store that salt along with the encrypted password. Hence, it is obvious to get different encoded results for the same string. But one common thing is that everytime it generates a String of length 60.
For bcrypt encryption, first enter the plain text that you want to encrypt. It can be any plain text. Now select the salt round. Salt round represents the cost factor, and a cost factor is directly proportional to the amount of time needed to calculate a single BCrypt hash. Now you can submit the form to generate the bcrypt hash online for the plain text that you have entered.
Similarly, to match a hashed password, you require providing the hashed password and the plain text to match with. Doing so the tool will compare both inputs and give a result whether the hashed password and plain text matched or not as true and false.
There is a difference between Hashed which start with "2y" and others which start with "2a." they are different variants of BCrypt from improvements over the years, some old implementations will not work with the newer ones as such I had to use this older implementation of 2a and 4 rounds to replace a hash in a db for some older software, so I could get in vs other sites which use 2y.
Ideally, the older implementation should be replaced with a newer one and use more rounds over time. This can be facilitated by re-hashing the users plain text password on the next login with the new way, you can do a string check on the first 6 characters (or better yet split by $ and look at the first two indices).
This MD5 hash generator is useful for encoding passwords, credit cards numbers and other sensitive date into MySQL, Postgress or other databases. PHP programmers, ASP programmers and anyone developing on MySQL, SQL, Postgress or similar should find this online tool an especially handy resource.
An MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm will always result in the same 128-bit hash output. MD5 hashes are commonly used with smaller strings when storing passwords, credit card numbers or other sensitive data in databases such as the popular MySQL. This tool provides a quick and easy way to encode an MD5 hash from a simple string of up to 256 characters in length.
MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hash algorithm always produces the same output for the same given input, users can compare a hash of the source file with a newly created hash of the destination file to check that it is intact and unmodified.
An MD5 hash is NOT encryption. It is simply a fingerprint of the given input. However, it is a one-way transaction and as such it is almost impossible to reverse engineer an MD5 hash to retrieve the original string.
Use this tools to hash a string into a message digested MD5 hash. This is a quick way for you to verify a hash you are creating is correct. If you are using salt, make sure to include that in the string.
MD5 is a 128 bit "message-digest" algorithm that was released in 1991. It creates a 16 byte hash value for the input of the algorithm. MD5 is one-way, meaning that the original input cannot be be determined simply by knowing the hash value. MD5 was also intended to be collision resistant, meaning that two inputs could not have the same hash value, until 2004 when it was determined not to be resistant.
MD5 is often used as a checksum algorithm. Text or files are fed into the MD5 algorithm and the resulting hash would change if the file had been changed. This is done to detect malicious tampering, or file corruption.MD5 has also historically been used as a password hashing algorithm. Password hashing algorithms allow a password to be stored, in a website's database for instance, without having to store the actual password. This makes it more difficult to steal passwords, and if the hash is taken, the user's password is not necessarily compromised. When using a hashing algorithm for passwords it is wise to use "salt". With MD5, salt is added by concatinating a string unrelated to the password to the user supplied password string. MD5 has since been deemed too weak for this, and was succeeded by SHA-1 and then SHA-2.
In most cases, the only way out is via the database. WordPress stores the passwords in the database in encrypted form for security reasons. It is therefore not possible to simply read or replace them. First you have to encrypt the password using the WordPress hash algorithm.
We simply wanted to offer an alternative option here, as we have often experienced that users use special characters or Cyrillic characters, for example, which are difficult to recognize. We have therefore decided to generate both SQL statements for you as a template so that one of the two SQL statements will help you to recover the password if the worst comes to the worst.
