Hi, I've spent some time reading manpages and examples in vain; I cannot figure out how the key modes function in mcrypt. I would like to know what input mcrypt expects and what's done to the key internally before encryption. 1. What´s the default input format? Binary? Hex? String? 2. Is the key hashed (SHA-1? as told in an old manpage), padded/truncated to fit the algoritm? I'm encrypting with a password (string). If I stick to the default key mode, should the key passed to mcrypt be in binary form? Should it be truncated to the appropriate length? I've tested to hash the key to HEX, trunkate it and binarise it with pack (as in the example in the manpage). As an alternative I've tested to hash it directly to binary form and not truncate. Both ways work as a charm, but are not compatible: the same password cannot decrypt both variants. Ideally I would like to use some keywrapping eg PBKDF2. What key mode would be appropriate? How to proceed? Yours, Per Tunedal |

Hello everyone!
I have a client server program in C that encrypts/decrypts data with
libmcrypt. The client encrypts the string that wants to send to server,
send it, and after the server reads, decrypts it. Bellow are my encrypt and
decrypt function:
*encrypt function:*
*void encrypt(char *es, char *key, char *civ, size_t length) {//es - string
to encrypt, length - the length of es
MCRYPT td;
int n;
td = mcrypt_module_open(MCRYPT_TWOFISH, NULL, MCRYPT_CFB, NULL );
if (td == MCRYPT_FAILED) {
log_err(log_opts, strerror(errno));
exit(1);
}
n = mcrypt_enc_get_iv_size(td);
char iv[n + 1];
strncpy(iv, civ, n);
iv[n] = '\0';
if ((mcrypt_generic_init(td, key, KEY_SIZE, iv)) < 0) {
log_err(log_opts, "while trying to do mcrypt_generic_init.");
exit(1);
}
mcrypt_generic(td, es, length);
if (mcrypt_module_close(td) < 0) {
log_err(log_opts, "while trying to close module.");
exit(1);
}
}*
*decrypt function:
**void decrypt(char *ds, char *key, char *civ, size_t length) {
MCRYPT td;
int n;
td = mcrypt_module_open(MCRYPT_TWOFISH, NULL, MCRYPT_CFB, NULL );
n = mcrypt_enc_get_iv_size(td);
char iv[n + 1];
strncpy(iv, civ, n);
iv[n] = '\0';
if ((mcrypt_generic_init(td, key, KEY_SIZE, iv)) < 0) {
log_err(log_opts, "trying to do mcrypt_generic_init.");
exit(1);
}
mdecrypt_generic(td, ds, length);
if (mcrypt_module_close(td) < 0) {
log_err(log_opts, "while trying to close module.");
exit(1);
}
}*
*My problem:*
There are cases when a string encrypted does not get the previous result
when decrypted. Can anyone suggest my where the problem can come from?
Thanks in advance!

I have a .txt file here encrypted from my phone and... I've forgotten the password. But it's only 3 letters, probably easier to guess on a full sized keyboard. In research I found the program used to encrypt it uses rc6. At first I thought mcrypt would be able to decrypt straight away. Now I see I need to specify the algorithm. But I can't see rc6 from --list. So more reading and I see that rc6 is propitiatory. More reading still on mcrypt and I see rc6 referred to as `encumbered`. I take it that this is referring to that irritating propitiatory status.... which is why rc6 isn't listed by --list, because the code had to be removed. ...so I guess I have to write the code in myself and patch it in... I thought I'd try arcfour but it doesn't have ECB-Mode... (patent background: http://lists.mindrot.org/pipermail/openssh-unix-dev/2000-December/003793.html ) I don't think I'll be choosing the phone program to encrypt stuff again! |

Jonathan, I need to compile this in 64 bit as soon as possible.....Thanks for answer me so quickly.. :) I suppose I should make changes in some flags to generate makefiles that then make compile in 64 bits, but i don't know exactly where do it I' m waiting for tips or a guide tu solve it.

Hi, I want to install libmcrypt-2.5.8 in a HP UX Operating system for 64 bits. Release: HP-UX B.11.31 Machine: ia64 Nowadays i have the default installation but it generates me a 32 bits library. >file libmcrypt.so libmcrypt.so: ELF-32 shared object file - IA64 > What have i change have to do in the installation(Makefile/configure files) to compile this in 64 bits? I need this library compiled in 64 bits. Can you help me with that? Thanks a lot. Lu.- |

Hi, I am trying to encrypt a file using aes 128 in cbc mode, using pkcs7 padding, with a specified 16 byte initialization vector. I believe that pkcs7 padding is on by default. And that rijndael-128 mode is equivalent to aes 128. How may I set the initialization vector? Thanks!! |

Hello all, I managed to compile and install libmcrypt 2.5.8 on tru64 unix 5.1b. I installed it despite the failing of one of the tests: Making check in src make check-TESTS Stack overflow: pid 77268, proc lt-ciphertest, addr 0x11f7fdff0, pc 0x3ffbffcc74c sh: 77268 Memory fault - core dumped FAIL: ciphertest AES tests (CFB, nCFB, nOFB, CTR) were successful.

There are some regression bugs in the current version.
I promise, I really do promise, that a new version
will be out soon that clears these up. The same is
true of mhash.

I seem to have run into a bug in which binary files encrypted in OpenPGP format with the latest versions of mcrypt and libmcrypt can't be decrypted. This is unfortunate since I have some data encrypted in this format that I would like back. I built libmcrypt-2.5.8 and mcrypt-2.6.7, then ran the following test. Note that in each case, I'm just hitting enter at the "Enter passphrase:" prompt. el@paprika ~/tmp/mcrypt-2.6.7/src $ dd if=/dev/zero of=testfile count=1 1+0 records in 1+0 records out 512 bytes (512 B) copied, 6.3584e-05 s, 8.1 MB/s el@paprika ~/tmp/mcrypt-2.6.7/src $ ./mcrypt testfile Enter the passphrase (maximum of 512 characters) Please use a combination of upper and lower case letters and numbers. Enter passphrase: Enter passphrase: File testfile was encrypted. el@paprika ~/tmp/mcrypt-2.6.7/src $ ./mcrypt -d testfile.nc mcrypt: testfile already exists; do you wish to overwrite (y or n)?y Enter passphrase: decryption: wrong key. File testfile.nc was NOT decrypted successfully. This has also been reported as a Gentoo bug: http://bugs.gentoo.org/show_bug.cgi?id=213088 Any advice? Thanks in advance. -- Elliot Kendall <eke...@br...> Network Security Architect Brandeis University Trouble replying? See http://people.brandeis.edu/~ekendall/sign/ |

Thanks for bringing this up.
I'll check to see what's happening here. There's some
outstanding bugs I really need to fix in the
mcrypt/mhash family, so I'll take this opportunity to
do a thorough work-through of the code.

I have tried to use crypto++ and openssl to get the same result as
mcrypt for a simple CFB crypto. The reason is I am trying to write a new
client for an existing server that use mcrypt, and mcrypt is not
"easily" available for windows.
The result from mcrypt is:
0xa7, 0x8f, 0x88, 0x4e, ...
Where-as the result from crypto++ and openssl is:
0xa7, 0x44, 0x24, 0x6e, ...
As you can see the first byte is the same but the following ones are
not. I am by no means an expert on neither mcrypt nor cryptography but
AFAIK using cfb should result in the same result so either I am doing
something wrong with mcrypt or something is wrong.
