| 1 | 00 padding |
| Message padding used for block cipher algorithms. Binary 0 are padded to fill a message up to a block length. The block length is implicit 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). Note: 1. This code value will be removed effective with the second release of the service code list in 2002. |
| 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 9796 #1 padding |
| Message padding for digital signature schemes according to ISO 9796 part 1. |
| 7 | ISO 9796 #2 padding |
| Message padding for digital signature schemes according to ISO 9796 part 2. |
| 8 | ISO 9796 #3 padding |
| Message padding for digital signature schemes according to ISO 9796 part 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). Note: 1. This code value will be removed effective with the second release of the service code list in 2002. |
|
| 11 |
| PKCS #1 signature padding |
| Message padding for digital signature schemes according to PKCS #1 (published by RSA Inc, 1993). Note: 1. This code value will be removed effective with the second release of the service code list in 2002. |
| 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. |
