ClientSessionKey

psrp_rs::crypto

Struct ClientSessionKey 

Source 
pub struct ClientSessionKey { /* private fields */ }
Expand description

Client-side RSA key used for PSRP session-key negotiation.

Implementations§

Source§

impl ClientSessionKey

Source

pub fn generate() -> Result<Self>

Generate a fresh 2048-bit RSA keypair.

Source

pub fn public_blob_hex(&self) -> String

Return the Windows PUBLICKEYBLOB representation of the public key that PSRP expects to transport via the PublicKey message.

Layout:

BLOBHEADER (12 bytes):
  bType = 0x06   (PUBLICKEYBLOB)
  bVersion = 0x02
  reserved = 0x0000
  aiKeyAlg = 0xa400 (CALG_RSA_KEYX)
RSAPUBKEY (12 bytes):
  magic = "RSA1"
  bitlen = 2048
  pubexp = u32 little-endian
modulus (256 bytes, little-endian)
Source

pub fn decrypt_session_key(&self, ciphertext: &[u8]) -> Result<[u8; 32]>

Decrypt an RSA-OAEP/SHA-1 wrapped session key and return the raw 32-byte AES key.
