Very slow decrypt
Hi Folks,
Currently restoring some data that has been encrypted using the naitive Solaris encrypt/decrypt commands. Taking ages, anyone used these before and are they usually really slow?
Thanks

Hi folks,
What will be the easy way to decrypt encrypted passwords on MySQL table. Googling brought me many suggestions on crypt/decrypt running scripts. Please advise. TIA

ENCRYPT(2) System Calls Manual ENCRYPT(2)
NAME
encrypt, decrypt, netcrypt - DES encryption
SYNOPSIS
#include <u.h>
#include <libc.h>
int encrypt(void *key, void *data, int len)
int decrypt(void *key, void *data, int len)
int netcrypt(void *key, void *data)
DESCRIPTION
Encrypt and decrypt perform DES encryption and decryption. Key is an array of DESKEYLEN (defined as 7 in <auth.h>) bytes containing the
encryption key. Data is an array of len bytes; it must be at least 8 bytes long. The bytes are encrypted or decrypted in place.
The DES algorithm encrypts an individual 8 byte block of data. Encrypt uses the following method to encrypt data longer than 8 bytes. The
first 8 bytes are encrypted as usual. The last byte of the encrypted result is prefixed to the next 7 unencrypted bytes to make the next 8
bytes to encrypt. This is repeated until fewer than 7 bytes remain unencrypted. Any remaining unencrypted bytes are encrypted with enough
of the preceding encrypted bytes to make a full 8 byte block. Decrypt uses the inverse algorithm.
Netcrypt performs the same encryption as a SecureNet Key. Data points to an ASCII string of decimal digits with numeric value between 0
and 10000. These digits are copied into an 8 byte buffer with trailing binary zero fill and encrypted as one DES block. The first four
bytes are each formatted as two digit ASCII hexadecimal numbers, and the string is copied into data.
SOURCE
/sys/src/libc/port
DIAGNOSTICS
These routines return 1 if the data was encrypted, and 0 if the encryption fails. Encrypt and decrypt fail if the data passed is less than
8 bytes long. Netcrypt can fail if it is passed invalid data.
SEE ALSO
securenet(8)
BUGS
The source is not included in public distributions. The implementation is broken in a way that makes it unsuitable for anything but
authentication.
