PADDING MECHANISM, CODED
Padding mechanism or padding scheme applied.
 
 
 
1
Zero padding
Message padding used for block cipher algorithms. Binary zeros are appended to the end of the message in order to make the message length an exact integer multiple of the block length. The block length is implicitly specified through the algorithm and mode of operation.
 
2
PKCS #1 padding
Message padding used for block cipher algorithms according to PKCS #1 (published by RSA Inc., 1993).
 
3
ISO 10126 padding
Message padding used for block cipher algorithms according to ISO-10126 specification.
 
4
TBSS padding
Message padding used for block cipher algorithms according to TBSS (Swiss standard, published by Telekurs AG, 1996).
 
5
FF padding
Message padding used for block cipher algorithms. Binary 255 are padded to fill a message up to a block length. The block length is implicit specified through the algorithm and mode of operation.
 
6
ISO/IEC 9796-1 padding
Message padding for digital signature schemes according to ISO/IEC 9796-1.
 
7
ISO/IEC 9796-2 padding
Message padding for digital signature schemes according to ISO/IEC 9796-2.
 
8
ISO/IEC 9796-3 padding
Message padding for digital signature schemes according to ISO/IEC 9796-3.
 
9
TBSS envelope padding
Message padding for digital envelopes according to TBSS (Swiss standard, published by Telekurs AG, 1996)
 
10
PKCS #1 envelope padding
Message padding for digital envelopes according to PKCS #1 (published by RSA Inc, 1993).
 
11
PKCS #1 signature padding
Message padding for digital signature schemes according to PKCS #1 (published by RSA Inc, 1993).
 
12
BCS signature padding
Message padding for digital signature schemes according to ZKA (German standard published by ZKA 1995).
 
13
OAEP
Optimal Asymmetric Encryption Padding (published in IEEE P1363).
 
14
RSAES-OAEP
Padding mechanism specified in PKCS#1, version2, for encryption with a RSA public key.
 
15
RSAES-PKCS#1-v1_5
Padding mechanism specified in PKCS#1, version2, for encryption with a RSA public key.
 
16
RSASA-PKCS-v1_5
Padding mechanism specified in PKCS#1, version2, for digital signatures.
 
17
Encryption Block Formatting
Padding mechanism specified in PKCS#1, version 1.5.
 
18
PKCS#5
Padding mechanism specified in PKCS#5 for symmetric encryption.
 
19
ANSI X9.23
Padding mechanism specified in ANSI X9.23 for symmetric encryption.
