PKCS#5 padding is identical to PKCS#7 padding, except that it has only been defined for block ciphers that use a 64-bit (8-byte) block size. In practice, the two can be used interchangeably. The maximum block size is 255, as it is the biggest number a byte can contain.
PKCS #6 1.5: Extended-Certificate Syntax Standard [5] Defines extensions to the old v1 X.509 certificate specification. Obsoleted by v3 of the same. PKCS #7: 1.5: Cryptographic Message Syntax Standard [6] See RFC 2315. Used to sign and/or encrypt messages under a PKI. Used also for certificate dissemination (for instance as a response to a PKCS ...
In cryptography, Optimal Asymmetric Encryption Padding (OAEP) is a padding scheme often used together with RSA encryption. OAEP was introduced by Bellare and Rogaway , [ 1 ] and subsequently standardized in PKCS#1 v2 and RFC 2437.
The attack relies on having a "padding oracle" who freely responds to queries about whether a message is correctly padded or not. The information could be directly given, or leaked through a side-channel. The earliest well-known attack that uses a padding oracle is Bleichenbacher's attack of 1998, which attacks RSA with PKCS #1 v1.5 padding. [1]
The latest version, 1.5, is available as RFC 2315. [1] An update to PKCS #7 is described in RFC 2630, [2] which was replaced in turn by RFC 3369, [3] RFC 3852 [4] and then by RFC 5652. [5] PKCS #7 files may be stored both as raw DER format or as PEM format.
The attack uses the padding as an oracle. [4] [5] PKCS #1 was subsequently updated in the release 2.0 and patches were issued to users wishing to continue using the old version of the standard. [3] However, the vulnerable padding scheme remains in use and has resulted in subsequent attacks:
RSA-PSS is an adaptation of their work and is standardized as part of PKCS#1 v2.1. In general, RSA-PSS should be used as a replacement for RSA-PKCS#1 v1.5.
The PKCS#11 standard originated from RSA Security along with its other PKCS standards in 1994. In 2013, RSA contributed the latest draft revision of the standard (PKCS#11 2.30) to OASIS to continue the work on the standard within the newly created OASIS PKCS11 Technical Committee. [3] The following list contains significant revision information:
