See code example in the toplevel rustdoc.

Functions

decrypt_inner 🔒

Removes the PKCS1v15 padding It returns one or zero in valid that indicates whether the plaintext was correctly structured. In either case, the plaintext is returned in em so that it may be read independently of whether it was valid in order to maintain constant memory access patterns. If the plaintext was valid then index contains the index of the original message in em.

non_zero_random_bytes 🔒

Fills the provided slice with random values, which are guaranteed to not be zero.

pkcs1v15_encrypt_pad 🔒

Applied the padding scheme from PKCS#1 v1.5 for encryption. The message must be no longer than the length of the public modulus minus 11 bytes.

pkcs1v15_encrypt_unpad 🔒

Removes the encryption padding scheme from PKCS#1 v1.5.

pkcs1v15_generate_prefix 🔒

prefix = 0x30 <oid_len + 8 + digest_len> 0x30 <oid_len + 4> 0x06 <oid_len> oid 0x05 0x00 0x04 <digest_len>

pkcs1v15_sign_pad 🔒
