Member Function Documentation

template<class EC, class MAC = HMAC<SHA>, class KDF = P1363_KDF2<SHA>>

unsigned int ECDecryptor<EC, MAC, KDF>::CipherTextLength ( unsigned int plainTextLength ) const [inline, virtual]

calculate length of ciphertext given length of plaintext.

Reimplemented from PK_CryptoSystem.
Definition at line 365 of file eccrypto.h.

template<class EC, class MAC = HMAC<SHA>, class KDF = P1363_KDF2<SHA>>

unsigned int ECDecryptor<EC, MAC, KDF>::Decrypt ( const byte * cipherText,

unsigned int cipherTextLength,

byte * plainText ) [inline, virtual]

decrypt a byte string, and return the length of plaintext.
Precondition: size of plainText == MaxPlainTextLength(cipherTextLength) bytes.
The function returns the actual length of the plaintext, or 0 if decryption fails.
Reimplemented from PK_Decryptor.
Definition at line 368 of file eccrypto.h.

template<class EC, class MAC = HMAC<SHA>, class KDF = P1363_KDF2<SHA>>

unsigned int ECDecryptor<EC, MAC, KDF>::MaxPlainTextLength ( unsigned int cipherTextLength ) const [inline, virtual]

maximum length of plaintext for a given ciphertext length.

Reimplemented from PK_CryptoSystem.
