Module nettle::rsa

The Rivest, Shamir, Adelman (RSA) cryptosystem.

Structs

PrivateKey	A private RSA key.
PublicKey	A public RSA key.

Constants

ASN1_OID_MD2	ASN.1 OID for MD2
ASN1_OID_MD5	ASN.1 OID for MD5
ASN1_OID_RIPEMD160	ASN.1 OID for RipeMD160
ASN1_OID_SHA1	ASN.1 OID for SHA1
ASN1_OID_SHA224	ASN.1 OID for SHA224
ASN1_OID_SHA256	ASN.1 OID for SHA256
ASN1_OID_SHA384	ASN.1 OID for SHA384
ASN1_OID_SHA512	ASN.1 OID for SHA512

Traits

Pkcs1Hash	Marker trait for hash algorithms usable for PKCS#1 signatures.
PssHash	A hash function usable for PSS.

Functions

decrypt_pkcs1	Decrypts ciphertext using public/private. Returns the resulting plaintext.
decrypt_pkcs1_insecure	Decrypts ciphertext using public/private. Returns the resulting plaintext.
encrypt_pkcs1	Encrypts plaintext using public, producing ciphertext. ciphertext must have the same size as the modulo of public.
generate_keypair	Generates a fresh RSA key pair usable for signing and encryption. The public modulo n will be modulo_size bits large. The public exponent is fixed to 0x10001.
sign_digest_pkcs1	Creates a PKCS#1.5 padded RSA signature for digest_info || digest.
sign_pkcs1	Signs the message hashed with hash using public/private, producing signature. The signature buffer is expected to be of the size of the modulo of public.
sign_pss	Signs the message hashed by hash using salt and the key pair public/private, producing signature. Expects signature to be the size of the modulo of public.
verify_digest_pkcs1	Verifies a PKCS#1.5 padded RSA signature for digest_info || digest.
verify_pkcs1	Verifies signature of the data hashed by hash using public. Returns true if the signature is valid.
verify_pss	Verifies signature of the data hashed by hash using a salt of salt_len bytes and the key public. Returns true if the signature is valid.
