See the DES - Data Encryption Standard crypto interface for description and examples.
Crete a checksum using DES in CBC encryption mode. This mode is only used for Kerberos 4, and it should stay that way.
The IV must always be diffrent for diffrent input data blocks.
Parameters:
in data to checksum
output the checksum
length length of data
ks key schedule to use
iv initial vector to use
Encrypt/decrypt a block using DES in Chain Block Cipher mode (cbc).
The IV must always be diffrent for diffrent input data blocks.
Parameters:
in data to encrypt
out data to encrypt
length length of data
ks key schedule to use
iv initial vector to use
encp if non zero, encrypt. if zero, decrypt.
Encrypt/decrypt using DES in cipher feedback mode with 64 bit feedback.
The IV must always be diffrent for diffrent input data blocks.
Parameters:
in data to encrypt
out data to encrypt
length length of data
ks key schedule to use
iv initial vector to use
num offset into in cipher block encryption/decryption stop last time.
encp if non zero, encrypt. if zero, decrypt.
Check if the key have correct parity.
Parameters:
key key to check the parity.
Returns:
1 on success, 0 on failure.
Encrypt/decrypt a block using triple DES using EDE mode, encrypt/decrypt/encrypt.
Parameters:
input data to encrypt
output data to encrypt
ks1 key schedule to use
ks2 key schedule to use
ks3 key schedule to use
encp if non zero, encrypt. if zero, decrypt.
Encrypt/decrypt a block using DES.
Parameters:
input data to encrypt
output data to encrypt
ks key schedule to use
encp if non zero, encrypt. if zero, decrypt.
Encrypt/decrypt using Triple DES in Chain Block Cipher mode (cbc).
The IV must always be diffrent for diffrent input data blocks.
Parameters:
in data to encrypt
out data to encrypt
length length of data
ks1 key schedule to use
ks2 key schedule to use
ks3 key schedule to use
iv initial vector to use
encp if non zero, encrypt. if zero, decrypt.
Encrypt/decrypt a block using DES. Also called ECB mode
Parameters:
u data to encrypt
ks key schedule to use
encp if non zero, encrypt. if zero, decrypt.
Seed the random number generator. Deprecated, use RAND - random number
Parameters:
seed a seed to seed that random number generate with.
Checks if the key is any of the weaks keys that makes DES attacks trival.
Parameters:
key key to check.
Returns:
1 if the key is weak, 0 otherwise.
Compatibility function for eay libdes, works just like DES_set_key_checked().
Parameters:
key a key to initialize the key schedule with.
ks a key schedule to initialize.
Returns:
0 on success, -1 on invalid parity, -2 on weak key.
Generate a random des key using a random block, fixup parity and skip weak keys.
Parameters:
key is set to a random key.
Returns:
0 on success, non zero on random number generator failure.
Encrypt/decrypt a block using DES in Propagating Cipher Block Chaining mode. This mode is only used for Kerberos 4, and it should stay that way.
The IV must always be diffrent for diffrent input data blocks.
Parameters:
in data to encrypt
out data to encrypt
length length of data
ks key schedule to use
iv initial vector to use
encp if non zero, encrypt. if zero, decrypt.
Generate a random key, deprecated since it doesn't return an error code, use DES_new_random_key().
Parameters:
key is set to a random key.
Setup a des key schedule from a key. Deprecated function, use DES_set_key_unchecked() or DES_set_key_checked() instead.
Parameters:
key a key to initialize the key schedule with.
ks a key schedule to initialize.
Returns:
0 on success
Just like DES_set_key_unchecked() except checking that the key is not weak for or have correct parity.
Parameters:
key a key to initialize the key schedule with.
ks a key schedule to initialize.
Returns:
0 on success, -1 on invalid parity, -2 on weak key.
Setup a des key schedule from a key. The key is no longer needed after this transaction and can cleared.
Does NOT check that the key is weak for or have wrong parity.
Parameters:
key a key to initialize the key schedule with.
ks a key schedule to initialize.
Returns:
0 on success
Set the parity of the key block, used to generate a des key from a random key. See DES key generation.
Parameters:
key key to fixup the parity for.
Convert a string to a DES key. Use something like PKCS5_PBKDF2_HMAC_SHA1() to create key from passwords.
Parameters:
str The string to convert to a key
key the resulting key
