var Curves = map[string]elliptic.Curve{
	"P224": elliptic.P224(),

Curves is a map of curve names to curves

Functions

func DecryptAESCBC

func DecryptAESCBC(key []byte, in []byte) ([]byte, error)

DecryptAESCBC - use a 128, 192, or 256 bit key to decrypt the given content using AES-CBC. The output will not be encoded. Empty content will not be decrypted.

This function is compatible with Helm's encryptAES function, when the input is base64-decoded, and when the key is 256 bits long.

func ECDSADerivePublicKey

func ECDSADerivePublicKey(privatekey []byte) ([]byte, error)

ECDSADerivePublicKey -

func ECDSAGenerateKey

func ECDSAGenerateKey(curve elliptic.Curve) ([]byte, error)

ECDSAGenerateKey -

func EncryptAESCBC

func EncryptAESCBC(key []byte, in []byte) ([]byte, error)

EncryptAESCBC - use a 128, 192, or 256 bit key to encrypt the given content using AES-CBC. The output will not be encoded. Usually the output would be base64-encoded for display. Empty content will not be encrypted.

This function is compatible with Helm's decryptAES function, when the output is base64-encoded, and when the key is 256 bits long.

func PBKDF2

func PBKDF2(password, salt []byte, iter, keylen int, hashFunc crypto.Hash) ([]byte, error)

PBKDF2 - Run the Password-Based Key Derivation Function #2 as defined in RFC 8018 (PKCS #5 v2.1)

func RSADecrypt

func RSADecrypt(key string, in []byte) ([]byte, error)

RSADecrypt - decrypt the ciphertext with the given private key. The key must be a PEM-encoded RSA private key in PKCS#1, ASN.1 DER form, typically beginning with "RSA PRIVATE KEY". The input text must be plain ciphertext, not base64-encoded.

func RSADerivePublicKey

func RSADerivePublicKey(privateKey []byte) ([]byte, error)

RSADerivePublicKey -

func RSAEncrypt

func RSAEncrypt(key string, in []byte) ([]byte, error)

RSAEncrypt - use the given public key to encrypt the given plaintext. The key should be a PEM-encoded RSA public key in PKIX, ASN.1 DER form, typically beginning with "PUBLIC KEY". PKCS#1 format is also supported as a fallback. The output will not be encoded, so consider base64-encoding it for display.

func RSAGenerateKey

func RSAGenerateKey(bits int) ([]byte, error)

RSAGenerateKey -

func StrToHash

func StrToHash(hash string) (crypto.Hash, error)

StrToHash - find a hash given a certain string
