Functions ¶
func DecodeAESKey ¶
DecodeAESKey decodes an aes_key from the protocol. Handles: direct hex (32 chars), base64(raw 16 bytes), base64(hex string 32 chars).
func DecryptAESECB ¶
DecryptAESECB decrypts AES-128-ECB ciphertext and removes PKCS7 padding.
func EncodeAESKeyBase64 ¶
EncodeAESKeyBase64 returns base64(hex) for CDNMedia.aes_key.
func EncodeAESKeyHex ¶
EncodeAESKeyHex returns the hex string of a key (for getuploadurl).
func EncryptAESECB ¶
EncryptAESECB encrypts plaintext with AES-128-ECB and PKCS7 padding.
func EncryptedSize ¶
EncryptedSize calculates the size after AES-128-ECB with PKCS7 padding.
func GenerateAESKey ¶
GenerateAESKey generates a random 16-byte AES key.
