If you don't specify the correct algorithm, OpenSSL either may spew garbage or complain about a bad magic number. openssl-dev Developers list for the OpenSSL Project 1.

Managing a CA with Openssl (These links all point to www.phildev.net - I am not associated with this site in anyway, but have found the content informative and easy to understand.) Many file formats are not intended to be read as text. Remove passphrase from a key: From: Dr Stephen Henson openssl enc -d -pass pass:your_passphrase -aes-256-cbc -in private.img.000 -out private.img.dec.000 > shown on the wiki, but even with what was definitely my encryption password, I'm getting bad magic number errors from openssl. The longer answer is that ASN1 structures can be encoded in a number of different ways. Re: fsck.ext4 Bad magic number in super-block while trying to open /dev/sde2 - Solved The old 12.2 installation was an out-of-the-box DVD Suse installation, however prior to 12.2 the machine had 11.1 on it which was too old to upgrade to 12.2, so I had to perform a new install at the time so the /boot partition was reformatted. That said, I'm using openssl_decrypt() to decrypt data that was only encrypted with openssl_encrypt(). AES - simple encrypt in Java, decrypt with openssl. openssl enc expects the input to have a header, consisting of the ASCII value Salted__ (that's the "magic number") followed by the 8-byte salt for the KDF. The problem is with the key. If such a file is accidentally viewed as a text file, its contents will be unintelligible. -name "*.pyc" -exec rm -f {} \; The command above will delete all pyc files recursively. The generated codes can be used for passwords, promotional codes, sweepstakes, serial numbers and much more. 2000-05-22 "OpenSSL des3....." returns "Bad magic number" ? In turn, when a passphrase is used by the openssl encryption routine, a magic and salt is put in front of the encrypted result. It's referring to arcane arts as opposed to holy magic. The class loader uses this to check you specify a valid file.-----== Posted via Deja News, The Leader in Internet Discussion ==----- 2000-05-22 Re: "OpenSSL des3....." returns "Bad magic number" ?

DK> Date: 2000-05-22 13:09:53 [Download RAW message or body ] Using WinNT4 and OpenSSL 0.9.5, I tried one of the examples in the docs: openssl des3 -salt -in file.txt -out file.des3 The password applied was "12345678". Again, stretching this out to some kind of race issue is another work of nonsense.) Contribute to openssl/openssl development by creating an account on GitHub. Magic Quotes Hiding PHP Keeping Current Features HTTP ... and the serial number of the client certificate. resize2fs: Bad magic number in super-block while trying to open /dev/xvda1 Couldn't find valid filesystem superblock. This note is primarily aimed at folks storing encrypted things in MySQL as I'm unfamiliar with other database setups. Author Topic: Issue of Nano images (BAD MAGIC NUMBER) still present on 20.1 (Read 393 times) One possibility is to have a new magic number and follow that with a password based encryption AlgorithmIdentifier instead of making up new formats for everything. org> Date: 2006-09-11 23:44:41 Message-ID: 20060911234440.GA6764 openssl ! It's saying "this is mysterious". The -k argument expects a passphrase, not a file. 2000-05-22 Re: "OpenSSL des3....." returns "Bad magic number" ? TLS/SSL and crypto library. down-6 james at NOSPAM dot gmail dot com ¶ 4 years ago. Details on homepage. I've not had to try to decrypt data where I do know for certain what the direct key is to know if I have an issue with bad pad blocks or any other exceptions which would indicate a key mismatch. Deploying application on master domain: site path: /srv/http/webapps/Main zipping _site to site.zip... decrypting ssh key... bad magic number Script failed with status 1 failed to deploy Some useful resources on openssl can be found at the links below: Openssl config file. If you own a Random Code Generator account, it can generate an unlimited amount of codes in batches of 250.000 each! For that reason, any files encrypted on Ubuntu 16.04 fail to be decrypted on Ubuntu 18.04. The openssl version command allows you to determine the version your system is currently using. If you store, for example, a credit card number that has been encrypted by openssl_public_encrypt inside of a database, the column type for the column you are storing the number in must be a blob. To quote one part: In turn, when a passphrase is used by the openssl encryption routine, a magic and salt is put in front of the encrypted result. Usually doing a clean on the pyc files solves this issue: find . If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 All three can be extracted directly from the client certificate. This is a convenience feature for CLI users, as it allows a single file to carry both the salt and the data. openssl-d Michael Sierchio 3.
