Constants

 

ASN1 Integer

CRYPT_RSA_ASN1_INTEGER 

 

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_EXPONENT

CRYPT_RSA_EXPONENT 

 

CRYPT_RSA_MODE

CRYPT_RSA_MODE 

 

To use the pure-PHP implementation

CRYPT_RSA_MODE_INTERNAL 

 

To use the OpenSSL library

CRYPT_RSA_MODE_OPENSSL 

(if enabled; otherwise, the internal implementation will be used)

 

PKCS#1 formatted private key

CRYPT_RSA_PRIVATE_FORMAT_PKCS1 

Used by OpenSSH

 

PuTTY formatted private key

CRYPT_RSA_PRIVATE_FORMAT_PUTTY 

 

XML formatted private key

CRYPT_RSA_PRIVATE_FORMAT_XML 

 

OpenSSH formatted public key

CRYPT_RSA_PUBLIC_FORMAT_OPENSSH 

Place in $HOME/.ssh/authorized_keys

 

PKCS#1 formatted public key

CRYPT_RSA_PUBLIC_FORMAT_PKCS1 

 

Raw public key

CRYPT_RSA_PUBLIC_FORMAT_RAW 

An array containing two Math_BigInteger objects.

The exponent can be indexed with any of the following:

0, e, exponent, publicExponent

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.
