Source0: https://mirrors.nju.edu.cn/pypi/web/packages/39/c6/400b6f20c0679fcca2d0d7d933e142d000a707a571a9068fd8297e88a781/Padding-0.5.tar.gz
BuildArch: noarch
%description
Append and remove padding to/from a string.
I. Functions:
appendPadding(str, blocksize=AES_blocksize, mode='CMS'):
Pad (append padding to) string for use with symmetric encryption algorithm
Input: (string) str - String to be padded
(int) blocksize - block size of the encryption algorithm. Usually 8 or 16 bytes
(string) mode - padding scheme one in (CMS, Bit, ZeroLen, Null, Space, Random)
Return:(string) Padded string according to chosen padding mode
removePadding(str, blocksize=AES_blocksize, mode='CMS'):
Remove padding from string
Input: (str) str - String to be padded
(int) blocksize - block size of the algorithm. Usually 8 or 16 bytes
(string) mode - padding scheme one in (CMS, Bit, ZeroLen, Null, Space, Random)
Return:(string) Decrypted string without padding
II. Blocksizes:
DES (Triple DES), CAST5 and Blowfish have block size of 64 bits = 8 bytes
DES_blocksize = 8
CAST5_blocksize = 8
Blowfish_blocksize = 8
AES has fixed block size of 128 bits = 16 bytes and this is the default blocksize
AES_blocksize = 16
III. Mode:
MODES ={
(0,'CMS') : 'Pad with bytes all of the same value as the number of padding bytes. Default mode used in Cryptographic Message Syntax (CMS as defined in RFC 5652, PKCS#5, PKCS#7 and RFC 1423 PEM)',
(1,'Bit') : 'BitPadding: Pad with 0x80 (10000000) followed by zero (null) bytes. Described in ANSI X.923 and ISO/IEC 9797-1',
(2,'ZeroLen') : 'Pad with zeroes except make the last byte equal to the number (length) of padding bytes',
(3,'Null') : 'Pad with null bytes. Only for encrypting of text data.',
(4,'Space') : 'Pad with spaces. Only for encrypting of text data.',
(5,'Random') : 'ISO 10126 Padding (withdrawn in 2007): Pad with random bytes + last byte equal to the number of padding bytes'
}
CMS mode is the default one
