As stated in the Firebug discussion group, Firebug’s Console panel currently (Firebug 2.x) cannot filter single messages out. You can only filter by messages matching a specific text using the search field. There are enhancement requests like issue #4507 reported to add such a filter, though it is unlikely that this will get implemented in … Read more
MD5 and SHA hashes in raw form are binary, however their common representation is a hex-encoded string, which contains characters [a-fA-F0-9]. So if this is what you meant, then characters G-Z, g-z are “excluded”. Another, less common, representation is Base64 encoding [0-9a-zA-Z+/].
The PHP function bin2hex means that it takes a string of bytes and encodes it as a hexadecimal number. In the Java code, you are trying to take a bunch of random bytes and decode them as a string using your platform’s default character encoding. That isn’t going to work, and if it did, it … Read more
In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don’t need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus … Read more
Fundamentally different. SHA1 is a hash algorithm, which is a one way function, turning an input of any size into a fixed-length output (160 bit in this case). A cryptographic hash function is one for which it should not be possible to find two inputs giving the same output except by brute force (for instance, … Read more
You may provide the password already hashed with md5, as said in the doc (CREATE ROLE): ENCRYPTED UNENCRYPTED These key words control whether the password is stored encrypted in the system catalogs. (If neither is specified, the default behavior is determined by the configuration parameter password_encryption.) If the presented password string is already in MD5-encrypted … Read more
Just go with: $ git cherry-pick another_branch This will cherry-pick the last commit from another_branch. Branches in git are just references to the last commit in that branch, you can use them instead of commit SHAs in your commands.
These short forms are just to simplify visual recognition and to make your life easier. Git doesn’t really truncate anything, internally everything will be handled with the complete value. You can use a partial SHA-1 at your convenience, though: Git is smart enough to figure out what commit you meant to type if you provide … Read more
I ran into the same issue trying to use DigestUtils in my Android app. This was the best answer I could find by searching, but I was reluctant to rebuild the .jar file with the namespace changed. After spending some time on this issue, I found an easier way to solve the problem for my … Read more
A git SHA hash is computed from different pieces of information: The tree it refers to; basically, the current content of the repository in the branch in which the commit appears. The SHA of the parent commit(s). The commit message. The author information: name, email and timestamp. The committer information: name, email and timestamp. Even … Read more
