ASN1 Sequence (with the constucted bit set)

CRYPT_RSA_ASN1_SEQUENCE 

 

CRYPT_RSA_COMMENT

CRYPT_RSA_COMMENT 

 

Use {@link http://en.wikipedia.org/wiki/Optimal_Asymmetric_Encryption_Padding Optimal Asymmetric Encryption Padding} (OAEP) for encryption / decryption.

CRYPT_RSA_ENCRYPTION_OAEP 

Uses sha1 by default.

see \global\Crypt_RSA::setHash()
see \global\Crypt_RSA::setMGFHash()
 

Use PKCS#1 padding.

CRYPT_RSA_ENCRYPTION_PKCS1 

Although CRYPT_RSA_ENCRYPTION_OAEP offers more security, including PKCS#1 padding is necessary for purposes of backwards compatability with protocols (like SSH-1) written before OAEP's introduction.

CRYPT_RSA_MODE

CRYPT_RSA_MODE

The modulus can be indexed with any of the following:

1, n, modulo, modulus

 

XML formatted public key

CRYPT_RSA_PUBLIC_FORMAT_XML 

 

Use the PKCS#1 scheme by default.

CRYPT_RSA_SIGNATURE_PKCS1 

Although CRYPT_RSA_SIGNATURE_PSS offers more security, including PKCS#1 signing is necessary for purposes of backwards compatability with protocols (like SSH-2) written before PSS's introduction.

 

Use the Probabilistic Signature Scheme for signing

CRYPT_RSA_SIGNATURE_PSS 

Uses sha1 by default.

CRYPT_RSA_SMALLEST_PRIME

CRYPT_RSA_SMALLEST_PRIME 

Functions

Generate a random value.

crypt_random(\optional $min, \optional $max) : Integer

On 32-bit machines, the largest distance that can exist between $min and $max is 2**31. If $min and $max are farther apart than that then the last ($max - range) numbers.

Depending on how this is being used, it may be worth while to write a replacement. For example, a PHP-based web app that stores its data in an SQL database can collect more entropy than this function can.

Parameters

$min

\optional

Integer $min

Constants

 

CRYPT_DES_MODE

CRYPT_DES_MODE 

 

Encrypt / decrypt using inner chaining

CRYPT_DES_MODE_3CBC

Encrypt / decrypt using outer chaining

CRYPT_DES_MODE_CBC3 

Outer chaining is used by SSH-2 and when the mode is set to CRYPT_DES_MODE_CBC.
